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.

Claim (Index 15):
An image heating apparatus comprising:\n an endless belt configured to heat a toner image on a recording material while feeding the recording material through a nip; a rotatable member configured to form the nip in cooperation with said endless belt; a heater including a heat generating element configured to generate heat by energization, said heater being configured to heat said endless belt; a detecting portion configured to detect a temperature of said endless belt in a region outside a minimum sheet passing region of said endless belt with respect to a longitudinal direction of said endless belt, wherein the minimum sheet passing region is a region of said endless belt in which with respect to the longitudinal direction, a minimum-size recording material of recording materials to be fed to the nip passes through the region; and a controller configured to control a temperature, at which energization to said heater is turned off, depending on a temperature rise rate per unit time of a detection temperature of said detecting portion, wherein when the temperature rise rate is a first rise rate, said controller turns off the energization to said heater in response to that the detection temperature reaches a first temperature, and when the temperature rise rate is a second rise rate lower than the first rise rate, said controller turns off the energization to said heater in response to that the detection temperature reaches a second temperature higher than the first temperature.
