PURPOSE:To raise initial potential, and to reduce dark decay, by adding an org. photoconductor made of a hydrazone compd. CONSTITUTION:A layer formed in a photoreceptor contains a hydrazone compd. represented by the right general formula in which R1 is disubstd. amino or alkoxy; R2 is optionally substd. alkyl; R3 is optionally substd. naphthyl; R4 is alkyl, aralkyl, or aryl, respectively optionally substd.; R5, R6 are each H, halogen, or a monovalent org. residue, such as alkyl, alkoxy, disubstd. amono, or acyl; and n is 0 or 1. |
