Conductive member and electrophotographic apparatus

摘要

The present invention provides a charging member for charging a body to be charged by bringing the charging member into contact with the body to be charged and applying a voltage between the body to be charged and the charging member. The charging member includes an elastic layer and a resin layer containing a conductive agent, wherein the resin layer is formed on the outer side of the elastic layer directly or indirectly via another layer. When the surface of the resin layer being in a state not containing any conductive agent is charged due to corona discharge generated by applying a voltage of 8 kV to a corona discharger disposed with a gap of 1 mm put between the surface of the resin layer and the corona discharger, a surface potential of the resin layer after an elapse of 0.3 sec is in a range of 50 V or less and a surface potential of the outermost resin layer after and elapse of 10 sec is in a range of 5 V or less. The present invention also provides a charging unit using the charging member.
