Abstract
An image forming apparatus according to an aspect of the present disclosure includes a fixing device and a controller. The fixing device includes a fixing member, a pressure member, a heating member, and a temperature sensor. The controller cuts off power supply to the heating member when the temperature detected by the temperature sensor has risen to a cutoff temperature higher than the target temperature and thereafter resumes power supply to the heating member when the detected temperature has fallen below the cutoff temperature, and performs the PID control while limiting a maximum power supplied to the heating member to an upper limit power, which is a power supplied to the heating member at the time when the detected temperature has risen to the cutoff temperature, during a period from when power supply is resumed until a predetermined specific period of time elapses.
