PROBLEM TO BE SOLVED: To provide a developing roller giving uniform electrifying property to toner in the developing roller visualizing an electrostatic latent image by toner by being brought into a pressurized contact with a photoreceptor which is used in an electrophotographic apparatus. SOLUTION: The problem is solved by the developing roller in which the amount of frictional electrification with polyamide film is 0 to 20nC. COPYRIGHT: (C)2006,JPO&NCIPI |
