PURPOSE:To form an image having the quality equal to the quality of an initial image even after continuous copying by using a (co)polymer contg. a specific monomer to coat at least the surface of a triboelectricity imparting member. CONSTITUTION:The polymer of the monomer expressed by the formula or the copolymer of the monomer expressed by the formula and vinyl monomer (e.g.; styrene) is coated on at least the surface of the triboelectricity imparting member for negative polarity which imparts triboelectricity to a toner. A carrier, toner conveying member 2 and elastic blade 3 are included in said member. The member is coated by coating a soln. of the above-mentioned (co)polymer to a base material of the above-mentioned member by dipping, spraying or brushing and drying the coating. Prepn. of the blade 3 or the like by adding carbon, etc., to the (co)polymer and molding the same is also possible. In the formula, R1 denotes H, lower alkyl; R2, R3 denotes lower alkyl, aryl, etc.; X denotes a combination group of C and P of the main chain. |
