Abstract: An electroded donor roll for mounting partially within a mixing chamber of a development unit for forming a development zone with an image bearing member and moving charged toner particles from the mixing chamber to the development zone. The donor roll includes a conductive shaft core and a dielectric material layer that is injection molded over the shaft core. The donor roll also includes axially extending electrodes formed in the surface of the dielectric layer, and robust commutator contact pads that are formed from a conductive commutator washer device which has been overmolded into the dielectric layer. The commutator pads each are in line with, and contact an axially extending electrode.
