Abstract:
An image heating apparatus includes: an endless belt for heating a toner image on a recording material in a nip; an exciting coil for heating the belt by electromagnetic induction heating; rotatable driving member for forming the nip between itself and the belt and for rotationally driving the belt; a magnetic flux suppressing member for suppressing magnetic flux when a predetermined recording material having a width narrower than a maximum-width recording material usable in the image heating apparatus is subjected to image heating, wherein the magnetic flux, of magnetic flux directed from the exciting coil toward the belt, is directed toward a part of a region outside, with respect to a widthwise direction of the belt, of a region where the belt is contactable to the predetermined recording material; and a rotatable heat-absorbing member for absorbing heat from the rotatable driving member in contact therewith.
