Abstract
A process for preparing a toner donor roll having an integral electrode pattern involving: (a) providing a cylindrically shaped insulating member; (b) coating the insulating member with a photo or thermally sensitive composition comprised of a polymeric material and a conductive metal nucleating agent; (c) patterning the composition, resulting in a first composition portion corresponding to the electrode pattern and a second composition portion; and (d) depositing conductive metal on the first composition portion, resulting in the electrode pattern which is capable of being electrically biased to detach toner particles from the donor roll. In an alternative embodiment, there is provided an insulating member comprised of an insulating polymeric material and a conductive metal nucleating agent.
