Abstract
The present invention provides an image heating apparatus comprising a heating member having a first heating resistor and a second heating resistor, a temperature detecting element for detecting a temperature of the heating member, and a power supply control means for controlling power supply to the first and second heating resistors so that detected temperature of the temperature detecting element is maintained a set temperature. The power supply control means sends the power supply to the first heating resistor in a first power supply pattern, and sends the power supply to the second heating resistor in a second power supply pattern different from the first power supply pattern.
