PURPOSE: To obtain the electrophotographic sensitive body having a high sensitivity and high durability by incorporating a specific heterocyclic compd. into a charge transfer layer.
CONSTITUTION: The heterocyclic compd. expressed by formula I is incorporated into the charge transfer layer. In the formula, R1 denotes a hydrogen atom, straight chain or branched alkyl group which may be substd., etc.; R2, R3 may be the same or different and denote a hydrogen atom, straight chain or branched alkyl group which may be substd., etc. or R2 and R3 form a ring together with the adjacent carbon atoms. A denotes a tervalent group consisting of a 5-atom heterocycle which may be condensed or substd. The photosensitive body which has a stable initial potential, small dark attenuation, high sensitivity, small deterioration by repetition and excellent durability is obtd. in this way.
