    摘要： An electrophotographic imaging member including a supporting substrate; an optional charge blocking layer; an optional adhesive layer; a charge generating layer and at least two charge transport layers, each charge transport layer including a charge transporting polymer (a) including a backbone containing charge transporting moieties in the backbone, the moieties having a chemical structure different from the chemical structure of charge transporting moieties in the charge transport polymer of any charge transport layer lying closer to the charge generating layer, and (b) having a higher ionization potential than the charge transport polymer in any charge transport layer lying closer to the charge generating layer. This imaging member may be employed in an electrophotographic imaging process, particularly in high sensitivity infrared photoreceptors which are compatible with liquid ink development processes.
