ABSTRACT:
An electrophotographic developer roller with a highly resistive layer over a conductive core is made by mixing polyurethane and ferric chloride. After curing, the roller is soaked in hydrogen peroxide to oxidize the outer surface. The oxidized surface layer is electrically resistive. An excellent developer roller is achieved at low production cost.
