A charging member has a conductive core, a conductive elastic layer formed on the surface of the conductive core, and a wearing surface layer to be used also as a resistance controlling layer formed on the surface of the conductive elastic layer, and comprising a surface layer-forming resin and a resistance controlling conductive filler, developing conductivity by electron conduction and having a specific wearing amount of 5.0x10-4 (mm3/N.km) or more, the charging member capable of preventing deterioration of the charging performance of a charging member caused by contamination of the surface layer of the charging member, and maintaining stable and satisfactory uniform charging property and image quality for a long period of time, and always keeping the surface clean by positively wearing the surface layer of the charging member.
