PROBLEM TO BE SOLVED: To provide an image forming apparatus wherein deterioration in durability of a belt member is prevented since a good transfer nip part is formed and heat generated in a transfer fixing member is hardly transmitted to the belt member via the transfer nip part. SOLUTION: The image forming apparatus is provided with the transfer fixing member 67 wherein a toner image carried by the belt member 27 is transferred to be heated and melted. Among a plurality of roller members suspending the belt member 27, one roller member is a counter roller 28 brought into pressure contact with the transfer fixing member 67 via the belt member 27 to form the transfer nip part, and another roller member is an auxiliary roller 91 arranged in the vicinity of the counter roller 28 so that a winding angleθof the belt member 27 to the counter roller 28 becomes 90 degrees or lower.
