摘要

An improved electrophotographic photosensitive member has a conductive support; And the electrically conductive and includes a photoconductive element of the support positions, the photoconductive element is a charge transport material having the formula (a); And (b) a charge generating compound: ; Wherein, R _1, R _2, R _3, R _4, R ₅ and R ₆ are, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; X ₁ and X ₂ are each independently - (CH _2)n - group; X ₃ is a linking group; And Q _1, Q _2, Q _3, Q _4, Q _5, and Q ₆ are independently O, S, NR, or NC (= O) R ^', wherein R and ^R' are each independently H, respectively, alkyl group, alkenyl group, alkynyl group, heterocyclic group, or an aromatic group. Corresponding electrophotographic apparatus and image forming method is disclosed. ; Electrophotographic photosensitive member, the charge transport materials Hydra jongye
