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 10):
An image forming apparatus comprising:\n an image forming portion configured to form a toner image on a recording material; an endless belt configured to heat the toner image, formed on the recording material by said image forming portion, 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 sensor configured to detect a temperature of said heat generating element configured to heat 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; a double feed detecting portion configured to detect feeding of a plurality of recording materials to the nip; and a controller configured to control a temperature, at which energization to said heater is turned off, depending on a detection result of said double feed detecting portion, wherein when the feeding of the plurality of recording materials to the nip is detected by said double feed detecting portion, said controller turns off the energization to said heater in response to that the detection temperature of said sensor reaches a first temperature, and when the feeding of the plurality of recording materials to the nip is not detected by said double feed detecting portion, 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.
