An image heating apparatus includes: a belt for heating in a nip an image formed on a recording material; a rotatable steering member for stretching the belt and for controlling the position of the belt with respect to a widthwise direction by inclination; a slidable member provided so as to be movable toward and away from a surface of the belt; a contact and separation portion for moving the slidable member toward and away from the belt; an execution portion capable of executing an operation in a sliding mode in which the slidable member contacts the belt and is slid on the surface of the belt; and a controller for controlling a maximum inclination angle of the rotatable steering member during execution of the operation in the sliding mode so that the maximum inclination angle is set at a value smaller than that during image formation.
