摘要： A fixing device includes a cylindrical film, a planar heater, a heat conduction member, a supporting member, a limiting member for limiting heater end portions with respect to a generatrix direction of the film so as to prevent the end portions from moving in a heater thickness direction relative to the supporting member, and a pressing member. A fixing device state is switchable between a first state in which a press-contact force in the nip is enough to fix the toner image and a second state in which the press-contact force in the nip is smaller than the press-contact force in the first state. A surface where the supporting member opposes the heat conduction member has a shape such that with respect to the generatrix direction, a central portion of the film is projected toward the pressing member to a greater extent than an end portion of the film.

摘要： An image forming apparatus includes a transfer rotary member for forming a primary transfer portion between a photosensitive drum and an intermediate transfer belt. The transfer rotary member includes multiple rotary members whose diameters are different, into which the transfer rotary member is divided in a direction orthogonal to a moving direction of the intermediate transfer belt. The transfer rotary member is arranged so as to contact a surface of the intermediate transfer belt on a side opposite to a surface with which multiple photosensitive drums come into contact at the primary transfer portions, on a downstream side in the moving direction of the intermediate transfer belt with respect to a contact portion between the intermediate transfer belt and each photosensitive drum, the intermediate transfer belt being arranged so as to protrude on the photosensitive drum side.

摘要： A fixing device includes a frame, a film, a component portion engaging with the frame, and a roller that forms a nip with the film. The component portion includes a supporting portion provided inside the film, and including a first opposing surface opposing an inner surface of the film, and a second opposing surface opposing the inner surface of the film. Each of the first opposing surface and the second opposing surface is a surface forming a substantially right angle with an engaging surface, which is a surface on which the component portion engages with the frame and on which the component portion opposes a flat surface portion of the frame. When the component portion is seen in the longitudinal direction of the film, a contour of the first opposing surface is greater than a contour of the second opposing surface.
