Melting points of the compds. expressed by formulas III and IV are pref. <=100 deg.C. When a charge transfer layer is formed from a donative charge transfer material such as hydrazone, etc., and a polymer having an acceptive carbonyl group such as polyacrylate, etc., foots of an absorption spectrum are extended by the interaction to a long wavelength side. Similar phenomenon is caused when a polymer other than polymers having acceptive carbonyl groups is used. Thus, a range of selection for polymers is widened when a hydrazone compd. or a stilbene compd. is used as a charge transfer material, thus a superior electrophotographic sensitive body is obtd.
