ABSTRACT:
This invention relates to a novel organophotoreceptor that comprises an electrically conductive substrate and photoconductive element on the electrically conductive substrate, the photoconductive element havinga) a novel charge transport compound having the formulawhere X is a divalent hydrocarbon group of 1 to 30 carbon atoms, or a divalent hydrocarbon group of 1 to 30 carbon atoms where there is at least one substitution of a carbon atom by a heteroatom provided that no two heteroatoms may be adjacent within the backbone of an aliphatic divalent hydrocarbon radical, R1is an aryl group or a heterocyclic group, R2is a (N,N-disubstituted)arylamine group, and R3is an epoxy group; and(b) a charge generating compound.The epoxy group can be reacted with a functional group within the polymer to form a polymeric charge transport compound either directly or through a crosslinking agent.
