PURPOSE: To form a photosensitive body having high carrier generating efficiency and excellent photoconductivity and to form a satisfactorily visible image by incorporating a specific bis-azo compd. as an essential component into a charge generating phase and a styryl compd. or amine deriv. as an essential component into a charge transfer layer.
CONSTITUTION: The photosensitive body has a photosensitive layer 4 consisting of the carrier generating phase and carrier transfer phase. The carrier generating material (CGM) consisting essentially of the bis-azo compd. expressed by formula I [Ar1WAr3 are arom. cyclic groups, etc., R1WR4 are respectively H, electron attractive groups, A is formula II (X is OH, etc., Y is H, halogen, etc.)] is incorporated into the carrier generating phase at 20W40 proportion by pts.wt. to 100 a binder resin. The carrier transfer material (CTM) consisting essentially of at least either of the compd. expressed by formula III (R9, R10 are alkyl, etc., R11 is phenyl, etc., R12 is H, halogen, etc.) or the amine deriv. expressed by the formula IV (Ar4, Ar5 are phenyl, Ar6 is phenyl, naphthyl, etc.) is incorporated into the carrier transfer phase at 30W50 proportion to 100 the binder resin. The CGM and CTM may be provided as a single mixed layer 6 or may be provided as a separated function type on a carrier transfer layer 3.
