Image heating apparatus regulating a shift movement of an endless belt the inner face of which contacts a nip portion forming unit forming a nip portion with a roller contacting an outer face of the belt

摘要

The image heating apparatus includes an endless belt, a roller which contacts an outer face of the belt, and a nip portion forming unit which contacts an inner face of the belt, and forms a nip portion with the roller, for nipping and conveying a recording material. The nip portion forming unit includes a component which is longer than the belt in a generatrix direction of the belt. The apparatus also includes a regulation portion provided to oppose an end face of the belt, for regulating a shift movement of the belt to the generatrix direction of the belt. The regulation portion is integrally-molded with the component. As a result, damage of the end of the endless belt can be reduced.
