An electrophotographic photosensitive member having a conductive substrate and a photosensitive layer, which is characterized in that the photosensitive layer comprises a binder and at least one hydrazone compound represented by the following general formula (1) or (2): General formula (1) <IMAGE> In the formula; R11 and R12 independently of each other represent alkyl, aralkyl, or phenyl, each substituted or unsubstituted, or R11 and R12 form a 5- or 6-membered ring residue conjointly with the nitrogen atom to which they are bonded; R13 and R14 independently of each other represent alkyl or alkoxy; R15 and R16 independently of each other represent alkyl, aralkyl, or aryl, wherein the aralkyl and the aryl are substituted or unsubstituted; and n represents a integer of 0 or 1. General formula (2) <IMAGE> In the formula; R21 and R22 independently of each other represent alkyl, aralkyl, or phenyl, each substituted or unsubstituted, or R21 and R22 form a 5- or 6-membered ring residue conjointly with the nitrogen atom to which they are bonded; R23 and R24 independently of each other represent alkyl, aralkyl, or aryl, each substituted or unsubstituted; and Ar1 and Ar2 independently of each other represent substituted or unsubstituted arylene. |
