ABSTRACT:
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 p-diethylaminobenzaldehyde-(diphenylhydrazone), i.e., ##STR1## and the charge transport layer including DEASP or Acetosol Yellow in an amount not exceeding 13 wt. % of the hydrazone.
