PROBLEM TO BE SOLVED: To provide an image forming apparatus having a fixing device which maintains glossiness, without raising the lower limit temperature and which will not cause deviation in images, in the fixing device of a belt system. SOLUTION: The image forming apparatus has: the fixing device, which includes a support roller member parallel to a heating roller member and separated therefrom; a belt member stretched endlessly in between both of the roller members; and a pressure roller member disposed opposite the support roller member via the belt member. The pressure roller member and the support roller member constitute a second fixing process, and the abutment region between the pressure roller member and the belt member constitutes a first fixing process other than the region of the second fixing process. A pressing member is provided to a part of the first fixing process, so that the pressing force of the pressing member, with respect to the pressure roller member near the central part of the pressure roller, is larger than that near both the end parts.
