Patent ID: 6960418

Claim:
An organophotoreceptor 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 where R 1 , R 2 , R 3 , and R 4 are, independently, an alkyl group, an alkaryl group, or in aryl group; Y is an alkyl group, alkaryl group, or aryl group, and Y is at least trivalent; X is a linking group having the formula —(CH 2 ) 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 NR 3 group, a CHR 4 group, or a CR 5 R 6 group where R 3 , R 4, R 5 , and R 6 are, independently, H, hydroxyl group, thiol group, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group; and E is an epoxy group; and (b) a charge generating compound.
