    摘要： A charging member having a support, a conductive elastic layer formed on the support and a surface layer formed on the conductive elastic layer, wherein the surface layer contains a polysiloxane having an acrylic group and an oxyalkylene group. This provides a charging member to the surface of which toners and external additives used in the toners can not easily cling even because of repeated use over a long period of time and which therefore enables charging and image reproduction which are stable over a long period of time, even when used in the DC contact charging method; and further provides a process cartridge and an electrophotographic apparatus which have such a charging member.
