ABSTRACT:
An image forming apparatus is provided that has a first pressurizing member, a heating member, and a belt member laid across the heating member and the first pressurizing member in a tensioned state, the belt member being heated by the heating member. The apparatus also includes a second pressurizing member arranged at such position that the second pressurizing member is pressed against the first pressurizing member via the belt member, a fixing unit for fixing a developer image on a medium between the belt member and the second pressurizing member, and a heating control unit for controlling heating of the heating member to drive a temperature of the heating member toward a predetermined target temperature. In addition, the apparatus includes a first temperature detection unit for detecting the temperature of the first pressurizing member. The heating control unit determines the targeted temperature based on the temperature of the first pressurizing member detected by the first temperature detection unit.
