Abstract
An image heating apparatus includes a first heater for heating a first roller, a second heater for heating a second roller, a first sensor for detecting a temperature of a region of an endless belt supported by the first roller, a second sensor for detecting a temperature of a region of the endless belt supported by the second roller, and a controller for controlling energization to the first heater and to the second heater. The controller executes a first mode in which the energization to the first heater is controlled using an output of the first sensor and the energization to the second heater is controlled using an output of the second sensor, and a second mode in which the energization to the first heater and the second heater is controlled using the output of the first sensor without using the output of the second sensor.
