PURPOSE:To improve sensitivity and durability by using a specified hydrazone compd. as an electrostatic charge carrier transfer medium. CONSTITUTION:A hydrazone compd. contained in a photosensitive body and, preferably, being used in combination with a charge generating material, and it is represented by the formula, as shown here, in which R1 is H, lower alkyl, allyl, optionally substd. aryl or aralkyl; each of R1 and R2 is H, lower alkyl, lower alkoxy, aryloxy, or substd. amino; X is O, S, alkylamino, methylene, ethylene, or vinylene; Z is H, lower alkyl, lower alkoxy, or aryloxy; and (n) is 0 or 1. |
