Patent ID: 7427460

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 Ar is an aryl group; X comprises a bond or a linking group, wherein the linking group X is selected from the group consisting of —O—C(═O)— group and —O—CH 2 CH 2 O— group; R 1 and R 3 comprise, each independently, H, a carboxyl group, an amino group, a halogen, an acyl group, an alkoxy group, an alkylsulfanyl group, an alkenyl group, an alkynyl group, a heterocyclic group, or a part of a ring group; R 2 comprises H, a carboxyl group, an amino group, a halogen, an alkyl group, an acyl group, an alkoxy group, an alkylsulfanyl group, an alkenyl group, an alkynyl group, a heterocyclic group, an aromatic group, or a part of a ring group; R 4 comprises H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; and R 5 , R 6 , R 7 , and R 8 comprise, each independently, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, a heterocyclic group, or a part of a ring group; and (b) a charge generating compound.
