PURPOSE:To reduce toner soil so as to obtain a high quality image for a long period by providing a resin layer including carbon fiber, on a conductive elastic material. CONSTITUTION:A member for electrification has the shape of a roller, and is provided with a conductive supporting body 1 having the shape of shaft and a conductive elastic layer 2 provided around the supporting body, while a resin layer 3 is provided on the conductive elastic layer 2. The resin layer 3 is formed out of material for which carbon fiber is mixed with a binder resin. The thickness of the resin layer 3 is dependent on conditions such as the amount of carbon fiber mixed, however, it should preferably be 5-500mum, or specifically in the range of 20-200mum. By providing the resin layer, adhesion to an electron photograph photosentive material is reduced, and flexibility is ensured, while high quality image is obtained and toner soil is reduced, so that variation in volume resistance of the resin layer 3 can be reduced even in a low temperature and low humidity condition. |
