Abstract:
An image heating apparatus includes an endless belt, a rotatable member, a heater, a temperature detecting portion, and a controller configured to control a temperature, at which energization to the heater is turned off, depending on a temperature rise rate per unit time of a detection temperature of the temperature detecting portion. When the temperature rise rate is a first rise rate, the controller turns off the energization to the heater in response to that the detection temperature reaches a first temperature. When the temperature rise rate is a second rise rate lower than the first rise rate, the controller turns off the energization to the heater in response to that the detection temperature reaches a second temperature higher than the first temperature.
