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 charge transport compound having the formulaR1is an aromatic group, an alkyl group, an alkenyl group, or a heterocyclic group;R2comprises an (N,N-disubstituted)arylamine group;R3comprises an epoxy group;R4is H, an aromatic group, an alkyl group, an alkenyl group, or a heterocyclic group; andX is a first linking 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. Corresponding electrophotographic apparatuses and imaging methods are also described.
