The present invention provides organophotoreceptors comprising annelectrically conductive substrate and a photoconductive element on the electricallynconductive substrate, the photoconductive element comprising:n (a) a charge transport compound having the formulan nwhere R 1 and R 2 are, independently, hydrogen, an alkyl group, an alkaryl group or annaryl group; X is an aromatic group; Y is an (N,N-disubstituted)arylamine; Z is (CH 2 ) m ngroup where m is an integer between 0 and 30 where one or more of the methylenengroups is optionally replaced by O, S, C=O, O=C-O, O=C-NR 3 , sulfoxide, sulfate,nphosphate, an aryl group, urethane, urea, NR 4 group, CHR 5 group, or CR 6 R 7 groupnwhere R 3 , R 4 , R 5 , R 6 , and R 7 are, independently, H, hydroxyl, thiol, an amine group, annalkyl group, an alkaryl group, a heterocyclic group, or an aryl group, and E is a bond,nO, S, C=O, NR 8 , CR 9 R 10 group, a hetrocyclic group, or an aromatic group where R 8 ,nR 9 , and R 10 are, independently, H, an alkyl group, an alkaryl group, or an aryl group;nand (b) a charge generating compound. n Corresponding electrophotographic apparatuses and imaging methodsn(processes) are described, as are charge transport compounds. |
