摘要：
A fixing member including a base; a first elastic layer overlaid on an outer circumference of the base, the first elastic layer formed of a silicone rubber composition including a heat conductive filler and a micro-balloon, the heat conductive filler of the first elastic layer is a heat conductive needle shaped filler; a second elastic layer overlaid on an outer circumference of the first elastic layer, the second elastic layer formed of a silicone rubber composition including a heat conductive filler and a micro-balloon, the heat conductive filler of the second elastic layer is a heat conductive needle shaped filler and a heat conductive sphere shaped filler; and a release layer overlaid on an outer circumference of the second elastic layer. An amount of the heat conductive filler of the second elastic layer is larger than an amount of the heat conductive filler of the first elastic layer.
