    摘要: A charging member for use in a contact charging device which charges a charge-receiving member such as a photosensitive drum in a copier or printer by applying a voltage to the charging member and contacting the charging member to the charge-receiving member. The charging member includes at least an elastic layer and a surface layer disposed thereon which contacts the charge-receiving member. The surface layer includes at least a semiconductive resin and an insulating metal oxide contained in the semiconductive resin, and the surface layer has a maximum height of surface roughness (Rmax) of 10 .mu.m to 100 .mu.m.
