Abstract
An image heating apparatus includes a roller, a heating portion disposed within the roller, a bearing portion fitted around an end portion of the roller to rotably support the roller, and a retaining ring attached at an axially predetermined position of the roller to restrict the roller from moving in a axial direction of the roller with respect to the bearing portion. The retaining ring includes first and second projections fitted into a hole portion of the roller. Profiles of side surfaces of these first and second projections abutting edges of the hole portion in a circumferential direction are recessed in the circumferential direction.
