Abstract
An image heating apparatus has a heating member for heating an image on a recording material, a temperature detecting element for detecting the temperature of the heating member, and an electric power supply controller for phase-controlling an alternating current supplied to the heating member in conformity with the detected temperature by the temperature detecting element. The alternating current supplied to the heating member differs in electric power supply starting phase angle in each half wave.
