Introduction
Customer loyalty is important to banks and service firms because customer defections "can have more to do with a service company's profits than scale, market share, unit costs, and many other factors usually associated with competitive advantage".Banks serving private customers seek to reduce defections by building relationship Loyalty is an emotional relationship between the customers and the company.Therefore, loyalty is measured by the customer relationship strength.In competitive, complex & dynamic bank industry setting, only a small distinction in service providing, will cause a great transformation.Traditional banks, according to the principals of Relationship Marketing that consider the customers loyalty as its main goal, are going to be changed in to customer-based ones.In such dynamic setting, producing & setting strategies, which result in making customers loyal, is so important [1].Trust and satisfaction both are related to both behavioral and attitudinal loyalty.Satisfaction is positively related to repurchase intention and customer loyalty [2].Additional work by [3], finds that perceptions of commitment can lead to word-of-mouth communication, an aspect of attitudinal loyalty, and can result in future purchase intentions, an aspect of behavioral loyalty [4].

Theoretical Background
Customer loyalty is an important objective for strategic marketing planning and represents an important basis for developing a sustainable competitive advantage.Some researchers state that a positive relationship exists between loyalty of customers and performance of companies.Customer loyalty leads to increase business value and keeps business costs low as well.Increase in value and saving money mean lower time when companies seek for new customers.Many definitions about loyalty have two points in common; that is, behavioural aspect and attitudinal aspect [5].Behavioral loyalty is customer's repeated transaction and researches usually measure this aspect by observational techniques.Attitudinal loyalty has both positive effect on the relationship continuance, and the tendency to continue to remain in the relationship [6].Loyalty is a dedication on the part of the buyer to maintain a relationship and a devotion to buy the product or service repeatedly.Loyalty thus has a behavioral component which suggests a repurchase intention but also includes an attitudinal component which is based on preferences and impression of the partner.Trust can create benefits for the customers by decreasing transaction cost ultimately fostering customer loyalty to the relationship [7].Loyalty has been defined as "a deeply held commitment to rebury or repatronize a preferred product/service consistently in the future".

Loyalty and Satisfaction
Customer satisfaction is an overall attitude formed based on the experience after customers purchase a product or use a ser-vice [8].It is a reflection of being content with such a product or a service.Satisfaction is the assessment of the experience of interacting with a service provider up to the present time, and is used by customers to predict future experience [9].Satisfaction is a broad feeling, which is affected by service quality, product quality, price, and contextual and personal factors [10].Satisfaction is one of the antecedents of customer loyalty.satisfaction positively affects customer loyalty [11].Although the reason that customers remain loyal may not always be satisfaction [12], it is safe to say that satisfied customers are more loyal.

Loyalty and Trust
Trust has been studied extensively in literature.Trust has been defined as one party believing that the other party wills fulfill his or her needs.In terms of services, trust is the belief held by a customer that the service provider will provide the service that meets customer needs.A more general definition of trust is that a party has confidence in the honesty and reliability of his partner.This definition can be applied in different contexts, including exchanges of goods and services.Trust consists of two aspects: Perceived credibility and benevolence [13].There are two levels of trust, at the first level, the customer trusts one particular sales representative while at the second level, the customer trusts the institution [14].Trust is an important mediating factor between customer behavior before and after purchasing a product which can lead to long-term loyalty and strengthen the relationship between the two parties [15].As with loyalty, trust is a special psychological state that can only occur in certain relationships.When a customer trusts an organization, he or she has the confidence in service quality and product quality of the organization.Customers who trust an organization are more than likely to be loyal to the company.[16] point out that the precondition of customer loyalty is customer trust.In prior research, trust has been conceptualized as antecedent of satisfaction [17].

Loyalty and Commitment
Commitment is a pledge of continuity between relational partners [18] [19] points out that It may also be viewed as the attachment that one party perceives towards another party in a situation.At its core, commitment is an attitude towards the act of maintaining a relationship with a partner.Over the past years of relationship marketing scholarship, our understanding of commitment has significantly expanded.From a construct that had a limited definition, it is now regarded as a complex construct that includes multiple components.Many researchers in marketing have borrowed from the organizational behavior literature where there is a rich tradition of research on the organizational commitment construct.

Loyalty and Mental Image
An organization's image is an important variable that positively or negatively influences marketing activities.Image is considered to have the ability to influence customers' perception of the goods and services offered.Thus, image will have an impact on customers' buying behavior.Service literature identifies a number of factors that reflects image in the customer's mind.Image is considered to influence customers' minds through the combined effects of advertising, public relations, physical image, word-of-mouth, and their actual experiences with the goods and services.Similarly, [20], using numerous researches on service organizations, found that service quality was the single most important determinant of image.Thus, a customer's experience with the products and services is considered to be the most important factor that influences his/her mind in regard to image.Heung et al. found image to be an important factors, and to maintain a relatively high score rating among loyal customers.According to Mazanec image is positively associated with customer satisfaction and customer preference (a dimension of customer loyalty).

Relationship Quality
To create long-lasting customer relationships, relationship marketing, include marketing activities that attract, develop, maintain, and enhance customer relationships, has been utilized in a wide variety of industries.Customers care about the relationship as a whole and judge the relationship using past experience, expectations, predictions, goals, and desires.Relationship quality has been positively linked to customer loyalty.There is no unified definition of relationship quality.Relationship quality has been conceptualized as a construct consisting of several components.These components include satisfaction, trust, commitment, and overall quality among others [11].In the prior studies, satisfaction, trust are the most examined aspects of relationship quality [21].

Service Quality
Service managers need to understand how perceptions of their performance on service quality dimensions influence levels of customer satisfaction.The literature shows positive effects of customer satisfaction on such desirable outcomes as repeat purchase [22], retention, loyalty [23], retailer sales performance [24], and profitability [25].Discussion of service quality has resulted in the realization of the intangible, heterogeneous, and inseparable nature of the concept [26].Thus it is hard to measure it with the same measurement for product quality.Quite a few conceptualizations and measurements of service quality may be found in the literature.For example, it has been defined as consisting of two aspects :technical quality and functional quality [27].Service quality is also defined as the difference between customer expectation and the perception of service quality.Parasuraman et al. provided a list of their focus group studies with service providers and customers: access, communication, courtesy, competence, credibility, reliability, responsiveness, security, understanding and tangibles.In a later article they added that: "although the relative importance of the categories would vary from one service industry to the next, we believe the determinants of service quality in most (if not all) consumer service industries are included in this list."They then used the five dimensions tangible, reliability, responsiveness, assurance and empathy-as the basis for their service quality measurement instrument, SERVQUAL.However, some argue that measuring service quality using SERVQUAL, which is based on performance-minus-expectation (or gaps), is inappropriate and suggest that SERVPERE, which is performance-only measurement, is a better method [28].A third conceptualization of service quality includes interaction quality, physical environment quality, and outcome quality [29].Interaction quality includes attitude, behavior, and expertise.Physical environment quality includes ambient conditions, design, and social factors.Outcome quality includes waiting time, tangibles, and valence.In this study, service quality is defined as the whole service quality perceived by customers after using the service.Service quality is very important to customer satisfaction and trust.It is also one of the often studied antecedents of relationship quality.Service quality represents basic customer expectations, thus, a hygiene factor.In a study of service quality in banking, hospitals, and photo development, service quality was found to have a positive effect on relationship quality, which includes satisfaction and trust [30].Service quality is an important factor affecting customer satisfaction [31].The increase in customer's perceptions of service quality will influence aspects of relationship quality such as satisfaction and trust [32].In studying the 3C (computer, communication, and consumer electronic) retail industry in Taiwan, service quality has been shown to have a significant impact on trust [33].

The Conceptual Model of the Research
