PURPOSE:To obtain an electrophotographic sensitive body capable of retarding fluctuation of a light part potential and a dark part potential in a stage of forming continuous picture image by repetitive charge and exposure by incorporating a specified compd. into a photosensitive layer. CONSTITUTION:A compd. expressed by the formula I is incorporated into a photosensitive layer. In the formula I, each Ar1 and Ar2 is an aryl or heterocyclic group which may have a substituent, wherein at least one of Ar1 and Ar2 has a residue expressed by the formula II; each R1-R3 is an H atom, an alkyl group, etc. In the formula II, each R2 and R3 is an H atom, a (substituted) alkyl or (substituted)aryl group, etc., wherein R2 and R3 may form a 5- to 7-membered ring together with an N atom to be bonded. Thus, an electrophotographic sensitive body having high sensitivity and retarded fluctuation of a light part potential and a dark part potential when it is charged and exposed repeatedly, is obtd. |
