Abstract: An image forming apparatus includes image forming device for forming an unfixed image on a recording material; a fixing device for fixing the unfixed image on the recording material, the fixing device including a heater which is stationary in use, a film in sliding contact with the heater and a pressing member cooperative with the film to form a nip for receiving the recording material, and an opening portion for opening the apparatus for permitting jam clearance operation of the recording material in the fixing device. The pressing member and the film are separated from each other in association with opening of the opening portion.

Abstract: An image fixing apparatus includes a heater; a film in contact with the heater, wherein heat from the heater is applied through the film to a toner image on an image supporting member; and wherein the film is in contact with an entire heat generating area of a heater.

Abstract: An image heating apparatus includes a heater; a film movable in contact with a recording material carrying an image, wherein the image on the recording material is heated by heat from the heater through the film; a driving rotatable member for driving the film; wherein the driving rotatable member has a heat insulative surface layer.

Abstract: An electrophotographic copying apparatus is provided with a first body and a second body, the first body having a photosensitive member, a light source for exposing an original, an original supporting table movable relative to the light source with the original supported thereon, and a first optical system for projecting a first image information light reflected from the original onto the photosensitive member. The second body has a second optical system for projecting a second image information light onto the photosensitive member in the first body. Two copying modes are provided: a first mode for copying by the first image information light, and a second mode for copying by the second image information light. In the second mode, a controller positions a shutter member for blank exposure in the optical path in its retracted position prior to the copying in the second mode.

Abstract: An image fixing apparatus includes a heater; an endless film through which a toner image on a recording material is heated by heat produced by the heater; and a controller for controlling a position of the endless film in a direction perpendicular to a rotating directon of the endless film.
