PURPOSE:To increase selectivity of a polymer to be used in the title electrophotographic sensitive body for hydrazone and stilbene compd. and to make a design of the sensitive body easier, by incorporating a specified hydrazone compd. and/or a stilbene compd., together with an aromatic ketone and/or an aromatic ester in an electrophotographic sensitive body compsn. CONSTITUTION:The title electrophotographic sensitive body contains a hydrazone compd. expressed by formula I and/or a stilbene compd. expressed by formula II, together with an aromatic ketone expressed by formula III and/or an aromatic ester expressed by formula IV. 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. |
