Abstract
An image forming apparatus includes: a fuser unit, which includes a heating member heated by a heat source and a backup member; a temperature detector; and a control unit, which starts print control when a detected temperature reaches the fixing temperature while the temperature of the heating member is increasing to a fixing temperature, and which performs decreasing control when the detected temperature reaches a predetermined temperature higher than the fixing temperature. In a case that an increasing rate of the detected temperature at the beginning of the print control is equal to or less than a predetermined value, the control unit controls the heat source so that a heat quantity radiated from the heat source during the decreasing control becomes larger than that in the case that the increasing rate of the detected temperature at the beginning of the print control is larger than the predetermined value.
