Patent ID: 8064803

Claim:
A charging member comprising 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, and wherein the polysiloxane is a polysiloxane obtained through the following steps (I), (II) and (III): (I) the step of condensing by hydrolysis a hydrolyzable silane compound having a cationic-polymerizable group; (II) the step of adding to the condensation product obtained in the step (I) a compound which is a block copolymer synthesized from an acrylic monomer and a silicon monomer; and (III) the step of cleaving the cationic polymerizable group to cross-link the hydrolytic condensation product obtained in the step (II).
