Abstract
An image forming apparatus includes a heater, heating roller heated by the heater and a fixing belt heated by the heating roller. A thermistor detects a temperature of the fixing belt at an area where the belt is stretched by the heating roller. When a CPU receives a signal which instructs the stop of rotation of the fixing belt, the CPU continues rotation of the fixing belt until the detected temperature detected by the thermistor decreases a predetermined temperature in a case in which the detected temperature is higher than the predetermined temperature.
