  • Heat fixing member having core metal and release layer, heat and pressure fixing apparatus, and image forming apparatus
    Patent number: 6490429
    Abstract: The invention relates to a cylindrical heat fixing member in which in a fixing apparatus for fixing an unfixed toner image carried onto a recording material heats and pressurizes the recording material and which heat fixing member is formed by at least a release layer being formed on the peripheral surface of a core metal. In the heat fixing member, the thickness of the core metal is from 0.5 mm to 2.8 mm inclusive and the core metal material is an aluminum alloy that is elastically deformed by a stress of 60.0 Mpa at 210° C. The invention also relates to a heat and pressure fixing apparatus and an image formation apparatus using the heat fixing member.
