Photoreceptor containing dissimilar charge transporting small molecule and charge transporting polymer

摘要

An electrophotographic imaging member including a charge generating layer and a charge transport layer, the charge transport layer comprising a charge transporting small molecule dissolved or molecularly dispersed in a film forming charge transporting polymer comprising charge transporting moieties in the backbone of the film forming charge transporting polymer, the charge transporting moieties having a structure unlike the structure of the charge transporting small molecule, the ionization potential of the charge transporting small molecule and the charge transporting moieties having a difference in ionization potential value of less than about 0.05 electron volt, the charge transporting small molecule and the charge transporting polymer being non-absorbing to radiation in the region of intended use, and the charge transport layer being substantially free of electrically inactive film forming binder. This imaging member may be employed in an electrophotographic imaging process.
