METHOD FOR PRODUCING ROLLER, ROLLER, DEVELOPMENT ROLLER, DEVELOPMENT DEVICE, ELECTROPHOTOGRAPH PROCESSING CARTRIDGE, AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an inexpensive roller which has prescribed surface roughness and is reduced in thickness nonuniformity, a roller by the method, a development roller by the method, a development device having the development roller, and a process cartridge having the development device.;SOLUTION: The method for producing the roller whose surface is roughened and which has an elastic layer having a thickness exceeding 1 mm on the periphery of an axial core body, includes processes of: (a) forming an uncured liquid rubber material layer on the periphery of the axial core body; (b) the subjecting uncured liquid rubber material layer to heat treatment to make a semi-cured rubber material layer; and (c) contacting a heating member having a roughened contact surface with the semi-cured rubber material layer, so that the rubber material is surface-roughened and cured to make the elastic layer.;COPYRIGHT: (C)2007,JPO&INPIT
