Abstract
A donor member, useful in ionographic or electrophotographic apparatuses and preferably useful in hybrid scavengeless development units, has a substrate and an oxidized transport coating thereover. The oxidized transport coating includes a polymer binder, charge transporting molecules and one or more oxidizing agents. The polymer binder of the donor roll coating preferably includes one of (1) a crosslinked polymer with charge transporting molecules dispersed therein, or (2) a crosslinked polyamide binder with hydroxy charge transport molecules dispersed therein. The donor roll is preferably included in a printing machine that develops latent images formed on a photoconductive member.
