ABSTRACT:
An image forming apparatus includes a fixing unit and a fixing process managing system. The fixing process managing system, including a mode switchover unit, controls a time mode and a temperature mode for heating a fixing member. In the time mode, the fixing unit is determined to be ready for a fixing process when a given time elapses after activation of the image forming apparatus. In the temperature mode, the fixing unit is determined to be ready for a fixing process when a temperature of the fixing member attains a given reference temperature after activation of the image forming apparatus. The mode switchover unit selects between the temperature mode and the time mode. The fixing process managing system selects the temperature mode instead of the time mode when a supply amount of electrical power to the fixing unit is determined to be below a required electrical power supply level.
