ABSTRACT:
An image heating apparatus for heating an image on a recording material by heat generation of a heating member includes a coil configured to generate a magnetic flux by energization a heat generation member having an electroconductive layer that generates heat by magnetic flux for heating an image on a recording material and, a frequency switching device for switching a frequency of a current supplied to the coil. The electroconductive layer includes a first electroconductive member at a central portion thereof and a second electroconductive member at an end portion thereof. The first electroconductive member has a resistence characteristic, with respect to the frequency of the current supplied to the coil, different from that of the second electroconductive member.
