Improved organophotoreceptor comprises an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising:n (a) a charge transport compound having the formula nn nwhere R 1 and R 2 are, independently, hydrogen, an alkyl group, an alkaryl group or an aryl group; X is an aromatic group; Y is an (N,N-disubstituted)arylamine; Z is (CH 2 ) m group where m is an integer between 0 and 30 where one or more of the methylene groups is optionally replaced by O, S, C═O, O═C—O, O═C—NR 3 , sulfoxide, sulfate, phosphate, an aryl group, urethane, urea, NR 4 group, CHR 5 group, or CR 6 R 7 group where R 3 , R 4 , R 5 , R 6 , and R 7 are, independently, H, hydroxyl, thiol, an amine group, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group, and E is a bond, O, S, C═O, NR 8 , CR 9 R 10 group, a hetrocyclic group, or an aromatic group where R 8 , R 9 , and R 10 are, independently, H, an alkyl group, an alkaryl group, or an aryl group; andn (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described. |
