PURPOSE:To enhance sensitivity and to eliminate an induction effect by adding a hydrazone compd. as a sensitizer to a photosensitive layer prepared by dispersing a phthalocyanine type photoconductive powder into a binder resin. CONSTITUTION:A photosensitive layer prepd. by dispersing a phthalocyanine type photoconductive powder into a binder resin contains as a sensitizer a hydrazone compd. represented by general formula I in which R1 is -O(CH2)yCH3, (y is 0 or 1), a group having general formula II, (x is 0, 1, 2, or 3) or H; R2 is -OCH2CH3, -CH3, -CH2CH3, or -H; R3 is -H or -OCH2CH3; R4 is -H, -CH2CH3, or -CH3; R5 is -H or -CH3; R6 is formula III ; and R7 is formula IV ; and combined R6, R7 is presented by formula V. |
