    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 is 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 improve sensitivity and durability by forming a photosensitive layer contg. a specified 1,2,3,4-tetrahydroquinoline compd. on a conductive substrate. CONSTITUTION:Photosensitive layers 2, 2', 2'' formed on a conductive substrate 1 contains a 1,2,3,4-tetrahydroquinoline (THQ) compd. represented by the formula shown here in which A is an aromatic hydrocarbon or heterocyclic group; R1- R3 are each H, halogen, alkyl, aryl, or the like. The photosensitive layer 2 may be formed by using said THQ together with a sensitizing dye or an electron acceptor, and a binder, or the photosensitive layer 2' may be formed by dispersing a charge transfer substance 3 into a charge transfer layer composed of said THQ and the binder. The photosensitive layer 2'' of multilayer structure uses the THQ incorporated in the charge transfer layer 4. The THQ acts as a photoconductor in the photosensitive layer 2, and as a charge transfer medium in the photosensitive layers 2', 2''. As a result, these photosensitive layers are good in sensitivity, small in fluctuation, resistant against repeated uses, and rich in durability.
