An image heating apparatus includes: a rotatable heating member; a belt unit including an endless belt and first and second supporting members; a detector; a rotating mechanism; and a displacing mechanism for permitting displacement, with rotation of the belt unit by the rotating mechanism, of the first supporting member in a direction of equalizing forces urging the belt toward the rotatable heating member by the first supporting member at widthwise ends of the belt, and for permitting displacement, with rotation of the belt unit by the rotating mechanism, of the second supporting member in a direction of equalizing forces urging the belt toward the rotatable heating member by the second supporting member at the widthwise ends of the belt. |
