PURPOSE:To obtain satisfactory fundamental properties, mechanical strength, durability, and shelf stability as a photosensitive body by incorporating a specified hydrazone compd. in it. CONSTITUTION:A layer formed on a conductive substrate contains a compd. represented by general formula I in which R1 is H, halogen, optionally substd. alkyl or alkoxy; R2 is H, optionally substd. alkyl or aralkyl or aryl; R3, R4 are each optionally substd. alkyl or aralkyl or aryl; and n is 0 or 1. |
