ABSTRACT:
An image forming apparatus including a fixing device that has a rotatable endless belt, a contacting member to contact the rotatable endless belt, a rotatable pressing member contacting the contacting member via the rotatable endless belt to form a nip region, a heating member to heat the rotatable endless belt, a detecting device to detect a temperature of the heating member, a controlling device to control a temperature of the heating member based on a detection result of the detecting device, and a determining device to determine that the sheet-like recording medium has passed through the fixing device. The controlling device controls such that the temperature of the heating member set for the fixing operation is decreased to a temperature set when the sheet-like recording medium has passed through the fixing device, immediately after a last sheet-like recording medium in a series of a job has passed through the fixing device.
