Abstract: A photoconductive material, which is preferably in the form of a layer in an electrophotographic material, comprises (1) a polymerised heterocyclic vinyl compound, (for example poly-N-vinylcarbazole) or a polycondensed carbocyclic aromatic compound (for example a bromopyrene resin) as photoconductor, (2) an electron acceptor, (3) a subsequently crosslinkable binder and, (4) optionally, additives which improve the adhesion and/or the surface structure of the layer; wherein, the electron acceptor is present in an amount from about 0.1 to 0.5 mol per monomer unit of the photoconductor and the binder is present in an amount from about 30 to 120 parts by weight per 100 parts by weight of the photoconductor. A process for the preparation of the photoconductive layer is also described.
