    摘要： A method of manufacturing an electrophotographic seamless belt, includes setting a substantially cylindrical preform made of a thermoplastic resin mixture containing a thermoplastic resin and having an outer diameter “a”, in a seamless belt molding die including a cylindrical cavity having an inner diameter “b”, and stretch blow molding at a predetermined stretch temperature T1 to obtain a stretch-blow-molded part; and cutting the stretch-blow-molded part to obtain a seamless belt. The thermoplastic resin mixture has a temperature T2 at which a parameter S/P calculated from a tensile-stress to strain curve obtained by performing a JIS K7161 test on a sheet test piece made of the thermoplastic resin mixture is 2.0 to 15.0 T2 is set as the predetermined stretch temperature T1. P indicates stress when a stretch magnification is 0.6×(b/a) and S indicates stress when the stretch magnification is 1.6×(b/a) and (b/a)≧1.7.

    摘要： A charging member for charging a charge-receiving member, such as an electrophotographic photosensitive member, by disposing the charging member in contact with the charge-receiving member and applying a voltage to the charging member is constituted by disposing an electroconductive support, an elastic layer, and a surface coating layer having a tensile modulus of above 2000 kgf/cm.sup.2 to at most 30000 kgf/cm.sup.2 in this order. The coating layer may preferably contain an acrylic polymer-modified urethane resin. The charging member is effective in providing the charge-receiving member with a nip portion showing a uniform electric resistance distribution for a long period to provide excellent images.
