Abstract

PURPOSE:To enable uniform contact pressing and uniform charging without unevenness, by forming a contact material for charging the body to be charged by friction with short fiber specially oriented. CONSTITUTION:Cushion material 40, heater 41, insulator 42, electrode 43, conductive member 44, and short fiber 45 as a contact material are successively laminated in layers on the front of charger base 32 to the order from its surface facing the outer circumference of photoreceptor 4. Short fiber 45 is formed by flocking nylon fiber 49 on cotton fiber base 48, fiber 49 is slantly oriented reversely to the rotation direction of photoreceptor 4, and fiber base 48 is subjected to a water repelling treatment, thus permitting contact pressure of fiber 49 against photoreceptor 4 to be made uniform, its water resistance to be raised, and change of charging potential to be prevented.
