<p>HYDRAZONE CONTAINING CHARGE TRANSPORT ELEMENT AND PHOTOCONDUCTIVE PROCESS OF USING SAME A process for electrophotographic reproduction, and a layered electrophotographic plate having a conventional charge generation layer and a p-type hydrazone containing charge transport layer, in which the surface of the charge transport layer is selectively discharged by actinic radiation as a result of the migration through the transport layer of charges generated in the charge generation layer as a result of the actinic radiation and injected into the transport layer, the hydrazone having the composition; n=0,1 R1 = -O(CH2)yCH3 y=0, 1 X=0,1,2,3 R3 =-H-OCH2CH3 R4 =-H-CH2CH3 -H -CH3 R2 = -OCH2CH3 R5 =-H-CH3 -CH3 -CH3-CH2CH3 -H R6 = -CH2 -CH3 -CH2CH2CH2CH3 R7 = - CH3 R6 /A R7 =</p> |
