Abstract:
1. An image heating apparatus comprising: magnetic flux generating means having a coil for generating a magnetic flux; a rotatable heat generation member having an electroconductive layer for generating heat by the magnetic flux for heating an image on a recording material by the heat, said electroconductive layer having a thickness smaller than its skin depth; an electroconductive member which is disposed across said electroconductive layer from said magnetic flux generating means; and moving means for moving said electroconductive member to such a position that an end portion of an opposing portion of said heat generation member opposed to said coil is between said coil and said electroconductive member when a recording material having a width, measured in a direction perpendicular to a feeding direction of the recording material, is smaller than a maximum width of recording materials which can be processed by said apparatus.
