摘要

PROBLEM TO BE SOLVED: To provide a charge transport material, an organophotoreceptor with the same, an electrophotographic image forming apparatus, and an image forming method which uses the same.;SOLUTION: The organophotoreceptor includes an electrically conductive substrate and a photoconductive element located on the electrically conductive substrate, wherein the photoconductive element comprises (a) a charge transport material of Formula 1 and (b) a charge-generating compound. In the Formula 1, n is an integer between 3 and 6; R₁ and R₂ are, each independently, H, an alkyl group, an alkenyl group, an aromatic group or a heterocyclic group; R₃, R₄ and R₅ are, each independently, H, a thiol group, a hydroxyl group, a carboxyl group, an amino group, a halogen, a nitro group, a cyano group, an alkyl group, an alkenyl group, an aromatic group, a heterocyclic group or a part of a ring group; X₁ and X₂ are, each independently, a linking group; Y contains an arylamine group; and Z is a bridging group.;COPYRIGHT: (C)2005,JPO&NCIPI
