Abstract: An electrophotographic recording material is described that comprises an electrically conducting base layer and a photoconductive system deposited thereon, which system comprises an optional insulating intermediate layer, a layer containing a charge-generating compound, and a layer containing a charge-transporting compound mixed with binders, along with any sensitizers, acceptors and usual additives. The photoconductive system contains, as acceptor additive, one or more monomeric or polymeric compounds that have electron-attracting substitutents (halogen, cyano, nitro groups) and that are selected from the group consisting of anthracene, acridine, the anhydrides of phthalic acid, maleic acid, pyromellitic acid, benzophenonetetracarboxylic acid, and the polymers of vinyl chloride, vinylidine chloride and nitrocellulose, in a quantity of 0.2 to 10% by weight based on total coating weight.

Abstract: An electrophotographic recording material is comprised of an electrically conducting film base, an optional, adhesion-promoting, insulating intermediate film and at least one binder-containing photoconductive film that also contains a charge-carrier generating compound and pyrazoline charge-transporting compound represented by the formula ##STR1## in which n denotes zero or 1 andR.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 respectively denote hydrogen or halogen, preferably chlorine or bromine.Such a recording material has a low pre-exposure sensitivity combined with very good photosensitivity, and a low residual charge level in cyclic behavior. The charge-transporting compound has a low tendency to crystallize out in the film.
