Abstract:
An image heating apparatus includes a coil for generating magnetic flux; a rotatable heat generating member, having an electroconductive layer which generates heat by the magnetic flux, for heating an image on a recording material, wherein the coil has a length longer than that of the heat generating member with respect to a rotational axis direction of the heat generating member; and a magnetic member, provided oppositely to the coil at an end position of the heat generating member, having AC magnetic permeability of 1000 or more at 100 kHz.
