Abstract
An image heating apparatus includes a controller configured to control a temperature at which energization to a heater is turned off, depending on a detection temperature of a detecting portion, wherein, when a temperature rise rate per unit time of the detection temperature of the detecting portion is a first rise rate, the controller turns off the energization to the heater in response to the detection temperature reaching a first temperature, and, when the temperature rise rate per unit time is a second rise rate that is less than the first rise rate, the controller turns off the energization to the heater in response to the detection temperature reaching a second temperature that is greater than the first temperature.
