PURPOSE:To obtain an electrophotographic sensitive body having superior electrophotographic characteristics by incorporating a specified compd. as a charge transfer material of a photosensitive layer. CONSTITUTION:A compd. expressed by the formula I is incorporated as charge transfer material of a photosensitive layer formed on an electroconductive base body. In the formula I, X is a cyano group or an alkoxycarbonyl group; each R1 and R2 is an H atom, alkyl group, aryl group, alkoxycarbonyl group, aryloxycarbonyl group, nitro group, halogen atom, or arylcarbonyl group; each R3-R5 is an H atom, alkyl group, aralkyl group, aryl group, or a heterocyclic group; (m) is zero or 1; (n) is zero-2. Thus, a positively chargeable electrophotographic sensitive body having superior electrophotographic characteristics is obtd. |
