Abstract:
Provided are the following charging member and a method of producing the charging member. The charging member has an improved charging ability and hence alleviates, in particular, a positive ghost. The charging member can maintain resistance to the adhesion of toner, a toner external additive, or the like over a long time period. The charging member for an electrophotographic apparatus comprises an electro-conductive support, an electro-conductive elastic layer, and a surface layer, wherein the surface layer comprises a polymer compound having an Si—O—Ti linkage in a molecular structure thereof, and the polymer compound has each of constitutional units represented by a formula (1), a formula (2), and a formula (3) defined in the description. The method is a method of producing the charging member.
