ABSTRACT:
An electrophotographic developer roller is made by casting urethane prepolymer mixed with a butadiene, a trifunctional curative and ferric chloride powder. After curing, the roller is baked, which oxidizes the outer surface. The oxidized surface layer is electrically resistive, which is desirable in a developer roller. An excellent developer roller is achieved at low production cost.
