Abstract

An electrophotographic imaging member including a substrate, a charge generating layer, and a charge transport layer including a hole transport host material, a trace amount of a shallow trap dopant having a shallow trap electrochemical oxidation potential between about 0.02 volt and about 1.5 volts lower than that of the hole transport host and a film forming binder.
