Rubber charge roller cores are coated with styrene acrylic powder. Excess powder is removed, and the rollers are used in normal operation without the usual permanent outer layer. The more complex and costly outer layer of nylon is eliminated. Dust resulting from normal operation replaces the original powder coating.
