Filed: 1992-09-22
Abstract: PURPOSE:To satisfactorily carry a copy paper without winding the paper round a pressure roll without providing a separating claw by forming an elastic an elastic layer as the outermost layer and specifying the surface potential of the elastic layer to a specified value or lower. CONSTITUTION:An elastic layer is formed as the outermost layer of a pressure roll and the surface potential of the elastic layer is specified to <=100V when a copy paper is fed through between a fixing roll and a pressure roll facing to each other. For example, a silicone rubber layer 2 is formed as an inner layer on the outer peripheral surface of the core body 1, and a fluorine-contained rubber layer 3 having dispersed conducive agent and set to <=100V surface potential is formed as the outermost layer. Thus, the pressure roll has a two- layer structure. To set the surface potential of the fluorine-contained rubber layer 3 to <=100V, one or more of conductive agents of conductive metal oxides such as carbon black, tin oxide, and titanium oxide is dispersed in the material to form the fluorine-contained rubber layer.
