Abstract
A cellular conductive roller has closed cells and open cells with conductive powder filling the open cells of the cellular conductive roller. A method for making a cellular conductive roller includes filling the open cells in the cellular conductive roller with conductive powder, adhering a tacky sheet to the surface of said cellular conductive roller; then peeling said tacky sheet off the surface of said cellular conductive roller. Also disclosed is an electrophotographic device using the cellular conductive roller and a process cartridge into which the cellular conductive roller is integrated.
