PURPOSE:To improve the sensitivity and repetitive characteristics of a photosensitive body by incorporating a specific hydrazone compd. into a photosensitive layer. CONSTITUTION:The hydrazone compd. expressed by the formula 1 is incorporated as an electric charge transferable material into the photosensitive layer of the photosensitive body. In the formula, R1 denotes (substd.) aryl; R2-R6 denote H, halogen, alkyl, etc.; n denotes 0, 1. The compd. expressed by the formula II is usable as the compd. expressed by the formula. The photosensitive layer may be formed to both of a single layer type and lamination type. The sensitivity to a semiconductor laser is enhanced if a phthalocyanine compd., etc., are used as an electric charge generating material. |
