  • Publication number: 20140186078
    Abstract: 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 than an end portion of the film.

  • Publication number: 20130028622
    Abstract: The image heating apparatus includes an unit for spacing each of a buck-up member and a pressure roller apart from a flexible belt member which is electrified to generate heat, or heated by a source of heat at start-up, i.e. in a previous stage to heating an image, or an unit for controlling a pressure to decrease a contact area in the direction of the axis of rotation compared with the contact area for a period to heat an image. This can control, as much as possible, heat conduction from the flexible belt which is electrified to generate heat, or heated by the source of heat to the back-up member and the pressure roller at the start-up, i.e. the previous stage to heating an image.

  • Patent number: 6587662
    Abstract: In an oilless fixing apparatus of an image heating apparatus, a surface of a fixing roller or a pressure roller tends to be abraded by a separating claw if the contact pressure thereof is high, whereby the service life of the fixing roller or the pressure roller is often shortened. If the radius of curvature of the tip of the separating claw is reduced, there may be applied an excessively large force on the tip of the separating claw and the fixing roller or the pressure roller may be fatally damaged.
