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 transporting layer contains a specified diamine compound represented by general formula (I) below as the charge transporting substance. ##STR1## wherein R.sub.1 and R.sub.2, which are the same or different, each represent independently an alkyl group, an alkoxy group, or a halogen atom; R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which are the same or different, each represent independently an aryl group or an alkyl group, or R.sub.3 and R.sub.4, or R.sub.5 and R.sub.6, combine and form a condensed aromatic ring; and X represents an oxygen atom, a sulfur atom, a carbonyl group, or a sulfonyl group.
