METHOD FOR MANUFACTURING CONDUCTIVE RUBBER ROLLER AND CONDUCTIVE RUBBER ROLLER FOR ELECTRON PHOTOGRAPHY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a conductive rubber roller which shows reduced resistance dispersion in a longitudinal direction even in case the injection molding time is short, in manufacturing the conductive rubber roller using a liquid conductive rubber raw material with an injection molding device, and a conductive rubber roller for electron photography.;SOLUTION: This method reduces an injection amount of the liquid rubber raw material for forming an elastic layer per unit time at the time of ending the injection rather than at the time of starting the injection, in injecting the liquid rubber raw material into a cylindrical mold holding a shaft core.;COPYRIGHT: (C)2006,JPO&NCIPI
