    Abstract: A fixing device includes a rotatable endless fixing member that fixes a toner image onto a recording medium, and a heating member. The heating member includes a heat-generating layer that generates heat when supplied with electricity; an insulation layer that encloses the heat-generating layer therein to electrically insulate the heat-generating layer; a metallic layer that is laminated on a first surface of the insulation layer, has higher rigidity than the insulation layer, and generates an elastic restoring force; and a thermally conductive layer that is laminated on a second surface of the insulation layer, has lower rigidity than the metallic layer, and has higher thermal conductivity than the insulation layer and the metallic layer. The heating member is supported by one edge of the fixing member in a circumferential direction thereof, elastically deforms by being pressed against an inner peripheral surface of the fixing member, and heats the fixing member.

  • Patent number: 9098039
    Abstract: A roller-shaped rotator includes an endless belt and a roller-shaped base member. The roller-shaped base member is formed by winding a thin plate material plural times through elastic deformation into a roller shape. The roller-shaped base member is inserted into the endless belt, and brought into press contact with an inner peripheral surface of the belt by an elastic repulsive force due to the deformation. The roller-shaped base member is supported at both end portions in an axial direction so as to be rotatable about an axis of the roller-shaped base member.
