ABSTRACT:
An image heating apparatus has a flexible rotatable member, a slidable member contacting an internal surface of the flexible rotatable member, a holder for holding the slidable member, and a pressure roller for applying a pressure to the flexible rotatable member thereby forming a nip portion with the slidable member. A holding surface of the holder includes a first holding area of a crowned shape, and a second holding area of a crowned shape, which is provided at a downstream side of the first holding area in a moving direction of the flexible rotatable member, and the second holding area has a crown amount larger than a crown amount of the first holding area.
