Abstract
The fixing apparatus includes a sleeve, a nip portion forming member that contacts an inner surface of the sleeve, a pressure member, and a regulation member for regulating movement of the sleeve. The regulation member includes a first surface and a second surface. The first surface on an upstream side of the nip portion in a conveyance direction of the recording material includes a region in which the distance between the inner surface of the sleeve and the first surface in a radial direction of the sleeve increases toward a center portion of the sleeve in the generatrix direction, and in which the end surface of the sleeve contacts the region when the sleeve moves in the generatrix direction.
