Abstract
The present invention provides an image heating apparatus comprising a first heater, a second heater having a heat generating distribution different from that of the first heater, a heated member to be heated by the first heater and second heater, a temperature detection element for detecting a temperature of the heated member, and a power supply controlling means for controlling power supply to the first heater and second heater on the basis of a temperature detected by the temperature detection element. The power supply controlling means serves to stop the power supply to the first heater when the temperature detected by the temperature detection element reaches a first temperature, and to stop the power supply to the second heater when the temperature detected by the temperature detection element reaches a second temperature different from the first temperature.
