ABSTRACT:
The photoconductor for electrophotography comprises an electroconductive substrate and a photosensitive layer formed on the substrate. The photosensitive layer may be a monolayer or function-separated laminate type one which comprise a charge generating layer and a charge transporting layer laminated one on another. The charge generating layer contains a specified benzidine compound represented by general formula (I) below as the charge transporting substance. ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, 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 R.sub.1 and R.sub.2, or R.sub.3 and R.sub.4, or both combine and form a condensed aromatic group with the nitrogen atom to which they are bonded, respectively; R.sub.5 and R.sub.6 each represent independently a hydrogen atom, an alkyl group, an alkoxy group, or a halogen atom.
