ABSTRACT:
In a belt type fixing apparatus having a heat roller temperature sensor that detects the temperature of a heat roller that contains a heater for heating a fixing belt, and a fixing belt temperature sensor that is set to contact a pressure roller and indirectly detects the temperature of the fixing belt, the heater that heats the fixing belt is controlled in such a way that the temperature detected by the heat roller temperature sensor matches the target temperature of the heat roller that is set based on the temperature detected by the fixing belt temperature sensor.
