PURPOSE:To obtain an electrophotographic sensitive body having high sensitivity and high durability by incorporating a specified styryl compd. into a photosensitive layer. CONSTITUTION:A styryl compd. expressed by formula I is incorporated into a photosensitive layer formed on an electroconductive base body. In formula I, each R1 and R2 is H, alkyl group, aryl or styryl group which may have a substituent; R3 is an alkyl group, aralkyl or aryl group which may have a substituent; each R4 and R5 is H, alkyl, benzyl or phenyl group which may have a substituent; R6 is H, alkyl, alkoxy, or halogen. Thus, a photosensitive body having high chargeability and stable charge potential causing almost no deterioration of photosensitivity even if it is used repeatedly, is obtd. |
