Abstract
An image heating apparatus includes a heating member for heating an image on a recording material, a first temperature detecting element for detecting a first temperature of the heating member, a second temperature detecting element for detecting the second temperature of the heating member, wherein a thermal property of the second temperature detecting element differs from a thermal property of the first temperature detecting element, and a power supply controller for controlling the power supply to the heating member by utilizing the first temperature detecting element and the second temperature detecting element.
