Abstract:
An image heating apparatus comprising:a heating member for heating an image on a recording material;a first temperature detecting element for detecting a temperature of said heating member;a second temperature detecting element for detecting the temperature of said heating member, a thermal property of said second temperature detecting element differing from a thermal property of said first temperature detecting element; anda power supply control means for controlling an electrical power supplied to said heating member by utilizing said first temperature detecting element and said second temperature detecting element;wherein, when the temperature of said heating member is lower than a predetermined reference temperature, said power supply control means controls the electrical power in accordance with the temperature detected by said first temperature detecting element, and when the temperature of said heating member is not less than the reference temperature, said power supply control means controls the electrical power is accordance with the temperature detected by said second temperature detecting element.
