Abstract

An image forming apparatus includes an image forming portion; and a fixing portion. The fixing portion includes a cylindrical film, a nip-forming member and a roller including a shaft portion and an elastic layer. The elastic layer contacts an outer surface of the film except an end region of the film with respect to a generatrix direction. In the end region, the shaft portion and the outer surface of the film oppose each other with a spatial region with respect to a radial direction of the shaft portion. The image forming apparatus includes a spacer occupying at least a part of the spatial region.
