Abstract
A fixing control section of a fixing apparatus according to the present invention includes an end section priority temperature control mode. In the end section priority temperature control mode, the fixing control section temporarily turns off a main heater heating a center section of a fixing roller among a plurarity of heaters disposed inside the fixing roller in a case where a surface temperature of the end section of the fixing roller has reached a preset upper-limit fixing temperature, even if the surface temperature of the center section of the fixing roller is lower than a preset fixing temperature. As a result, destruction of the fixing roller can be prevented by a simple arrangement in the fixing apparatus which includes a plurarity of the heaters disposed inside the fixing roller.
