    摘要: The photoconductor for electrophotography (1) comprises an electroconductive substrate (2) and a photosensitive layer (3) formed on the substrate. The photosensitive layer (3) may be a monolayer or function-separated laminate type one which comprise a charge generating layer (3a) and a charge transporting layer (3b) laminated one on another. The charge generating layer (3a) contains a specified benzidine compound represented by general formula (I) below as the charge transporting substance.

    wherein R₁, R₂, R₃ and R₄, which are the same or different, each represent independently an aryl group, an alkylaryl group, an alkoxyaryl group or a halogenated aryl group provided that R₁ and R₂, or R₃ and R₄, or both combine and form a condensed aromatic group with the nitrogen atom to which they are bonded, respectively; R₅ and R₆ each represent independently a hydrogen atom, an alkyl group, an alkoxy group, or a halogen atom.
