MANUFACTURE OF DEVELOPING ROLLER FOR ELECTROPHOTOGRAPHIC DEVICE

PURPOSE:To uniformly distribute a conductive surface and a dielectric surface on the surface of a developing roller. CONSTITUTION:Dielectrics 40 are uniformly stuck to the surface of a conductive sheet 39 by printing. Thereafter, a conductive material 41 is stuck to the surface of the conductive sheet 39 by plating, and the dielectrics 40 are uniformly distributed in the conductive material 41. After that, the conductive sheet 41 is cut to proper size so as to form a cut sheet 38. Then, the cut sheet 38 is wound round and fixed on the roller body 33a of the developing roller 33.
