PURPOSE:To prevent deterioration of acceptance potential characteristics by incorporating a specified compound at least in a photosensitive layer formed on a conductive substrate and heat treating the obtained electrophotographic sensitive body in the inside of an image forming apparatus or in an outer device. CONSTITUTION:A good image can be obtained by incorporating in the photosensitive layer formed on the conductive substrate the compound represented by formula I or II in which Ar1 is an optionally substituted aromatic hydrocarbon or heterocyclic group; A is an optionally substituted N-substituted charbazolyl group or a group represented by formula III; R<3> is H, alkyl, alkocy, aryloxy, dialkylamino, diarylamino, or halogen; each of R<4> and R<5> is optionally substituted alkyl or aryl; Ar is an aromatic hydrocarbon group or heterocyclic group; and (n) is an integer of 1 or 2. |
