Abstract: PURPOSE:To obtain a good toner image by incorporating a specified hydrazone type compd. CONSTITUTION:A photosensitive body contains a compd. represented by formula I in which R1, R2 are each optionally substd. alkyl, aralkyl, or aryl, but both are not alkyl at the same time, and R3, R4 are each H, halogen, alkyl, or alkoxy. Said compd. can be applied to all the types of photosensitive bodies using org. photoconductive compds., and above all, preferably used for the electrostatic charge transfer layer of the photosensitive layer functionally divided into the charge generating layer and the transfer layer, and the transfer layer is preferably formed on the generating layer. Said compd. itself has no film forming ability, so it is mixed with a binder resin to form the transfer layer. Such a hydrazone type compd. transfers positive holes to inject the holes produced from the generating layer to the transfer layer, then they reach the surface to neutralize negative charge and form an electrostatic charged image, and a good toner image is formed on the surface of the photosensitive body with a positively charged developer. Such a photosensitive body is good in sensitivity, low in residual potential, small in its change even after repeated uses, and it can be used for not only copying machines but widely for laser printers, etc.

Abstract: PURPOSE:To obtain good sensitivity and decrease the fluctuation in the potential in a bright part and the potential in a dark part in repetitive electrostatic charging and exposing by providing a layer added with a specific hydrazone compd. CONSTITUTION:A layer added with the hydrazone compd. expressed by the formula is provided on an electrophotosensitive body. Such hydrazone compd. is used as an electric charge transfer material of the electrophotographic sensitive body of which, for example, the photosensitive layer is separated in function to an electric charge generating layer and an electric charge transfer layer. A soln. prepd. by dissolving such hydrazone compd. and a binder in a suitable solvent is coated and dried to form the charge transfer layer. The charge transfer layer may be laminated on the charge generating layer or may be laminated thereunder; the lamination on the charge generating layer is best preferred. Since the hydrazone compd. has a hole transferability, a positive chargeable toner is used. The photosensitive body contg. such charge transfer material has high sensitivity with the decreased fluctuation in the potential in the bright part and the potential in the dark part when used repeatedly and is used for not only a copying machine but a laser printer and photoengraving system, etc. as well.
