MEMBER FOR USE IN FIXING DEVICE, FIXING DEVICE, AND IMAGE FORMING APPARATUS

摘要

A member for use in a fixing device includes a base member that has a substantially cylindrical shape, and a covering member with which an outer peripheral surface of the base member is covered, the covering member including a first release layer that contains a first fluorocarbon resin and a second release layer that contains a second fluorocarbon resin and that is stacked on an area in the outer peripheral surface of the first release layer other than end portions of the outer peripheral surface of the first release layer in a width direction. In the covering member, a coefficient of kinetic friction of the outer peripheral surface of the first release layer that is exposed at ends of the member for use in a fixing device in the width direction is greater than a coefficient of kinetic friction of an outer peripheral surface of the second release layer.

1. A member for use in a fixing device comprising:
a base member that has a substantially cylindrical shape; and a covering member with which an outer peripheral surface of the base member is covered, the covering member including a first release layer that contains a first fluorocarbon resin and a second release layer that contains a second fluorocarbon resin and that is stacked on an area in the outer peripheral surface of the first release layer other than end portions of the outer peripheral surface of the first release layer in a width direction, wherein, in the covering member, a coefficient of kinetic friction of the outer peripheral surface of the first release layer that is exposed at ends of the member for use in a fixing device in the width direction is greater than a coefficient of kinetic friction of an outer peripheral surface of the second release layer.
