ABSTRACT:
An apparatus for charging an image transfer surface in an image transfer device includes a support member and a conductive polymer material surrounding an outer periphery of the support member. An inner portion of the conductive polymer material is loaded with a supplemental conducting agent, and an outer portion of the conductive polymer material is substantially free of the supplemental conducting agent.
