Abstract: PROBLEM TO BE SOLVED: To prevent a problem related on additive such is ion from occurring and to hold stable electrical conductivity within the range of desired resistivity by providing a bias system member with an electrical conductive core and an outer layer including a fluoroelastomer arranged on the core and filled with a carbon compound containing fluorine. SOLUTION: The bias system member is shaped like a roll and preferably basically formed like the rigid solid core 2 made of an electrical conductive metal. The electrical conductive metal is aluminum, copper, stainless steel or the like which can immediately respond to imparted bias potential, for example. The core 2 is covered with the coating 4 of the electrical conductive fluoroelastomer filled with the carbon compound containing the fluorine. By the coating 4, the ionizing of air in the contact area of a bias transfer part and a photoconductive body and around the area is restrained to the minimum. By covering the bias system member with the electrical conductive fluoroelastomer filled with the carbon compound containing the fluorine in such a way, the resistivity can be controlled.

Abstract: PROBLEM TO BE SOLVED: To attain satisfactory adaptation to transfer to a rough printing substrate as well as to ensure satisfactory peeling characteristics by forming an adaptation layer containing an electrically conductive or semiconductive polymer on a substrate and an arbitrary outer peeling layer on the adaptation layer. SOLUTION: The image separator 20 has a substrate 1, an adaptation layer 2 and an outer peeling layer 3. The substrate 1 contains an electrically conductive filler 4, the adaptation layer 2 contains an electrically conductive filler 5 and the outer peeling layer 3 contains an electrically conductive filler 6. The substrate 1 may be in the form of a belt, sheet, film or roll. The adaptation layer 2 may contain an adaptable electrically conductive material and/or an adaptable electrically semiconductive material. The outer peeling layer 3 is preferably a thin insulating peeling layer. A material suitable for the adaptation layer 2 is selected from fluoropolymers including Teflon and a fluoroelastomer, silicone materials such as silicone rubber, polyurethanes and mixtures of these.
