摘要

The present invention provides organophotoreceptors comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (a) a charge transport material having the formula CHEM where R1 and R2 are, independently, H, an alkyl group, an alkaryl group, or an aryl group; X is a linking group having the formula -(CH2)m-, branched or linear, where m is an integer between 1 and 20, inclusive, and one or more of the methylene groups is optionally replaced by O, S, C=O, O=S=O, a heterocyclic group, an aromatic group, urethane, urea, an ester group, a NR3 group, a CHR4 group, or a CR5R6 group where R3, R4, R5, and R6 are, independently, H, hydroxyl group, thiol group, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group; E is an epoxy group; and Z is a phenothiazine group, a phenoxazine group, a phenoxathiin group, a dibenzo(1,4)dioxin group, a thianthrene group, or a phenazine group; and (b) a charge generating compound. ??Corresponding electrophotographic apparatuses and imaging methods (processes) are described, as are corresponding charge transport materials.
