Development system coatings

This invention relates generally to overcoatings for ionographic or electrophotographic imaging and printing apparatuses and machines, and more particularly is directed to an effective overcoating for a donor means like a roll, preferably with electrodes closely spaced therein to form a toner cloud in the development zone to develop a latent image. The present invention is directed in embodiments to suitable charge relaxable overcoatings especially for the transport means in systems like scavengeless or hybrid scavengeless development systems, reference for example U.S. Pat. Nos. 4,868,600, 5,172,170, and copending patent applications U.S. Ser. No. 396,153 (now abandoned) and U.S. Ser. No. 724,242 now abandoned, the disclosures of which are totally incorporated herein by reference. A coated transport roll comprised of a core with a coating comprised of a charge transporting polymer and an oxidizing agent.
