Patent number: 7291431Abstract: This invention relates to a novel organophotoreceptor that comprises an electrically conductive substrate and photoconductive element on the electrically conductive substrate, the photoconductive element having a) a novel charge transport compound having the formula where 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, R1 is an aryl group or a heterocyclic group, R2 is a (N,N-disubstituted)arylamine group, and R3 is 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.Type: GrantFiled: March 2, 2006Date of Patent: November 6, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Zbigniew Tokarski, Nusrallah Jubran, Kam W.
