    Abstract: A fixing apparatus includes a back-up member contacting an inner surface of a cylindrical belt; a roller having an elastic layer and contacting an outer surface of the belt, the roller being cooperative with the back-up member to form a fixing nip between the belt and the roller. A sheet carrying a toner image is nipped and fed through the fixing nip, during which the unfixed toner image is heat-fixed thereon by the fixing nip. The back-up member includes a portion contactable with the inner surface and having such a configuration that the belt forms a first curved surface convex toward the roller in an upstream region in the fixing nip with respect to a moving direction of the belt and that the belt forms a second curved surface convex toward the back-up member in a downstream region in the fixing nip with respect to the moving direction.
