Abstract
The present invention relates to novel electrophotographic imaging systems and particularly to novel electrophotographic photoreceptors. These photoreceptors comprise a conductive substrate, an inorganic barrier-charge transport layer, and a photoconductive insulative layer. The barrier charge transport layer comprises aluminum oxide having a non-porous zone adjacent the substrate, and a porous charge transport zone.
