ABSTRACT:
An electrophotographic recording material comprising an electrically conductive base material, an option insulating intermediate layer, and a photoconductive double layer comprised of a charge-generating and a charge-transporting layer employs a pyrimido[5' ,4':5,6]-pyrido-[1,2-a]-benzimidazole transport compound, along with a binder and a dye or pigment, in the charge transporting layer, which compound is represented by the formula I ##STR1## wherein R.sub.1 and R.sub.2 are identical or different and denote hydrogen or an R.sub.3 R.sub.4 N group; R.sub.3 and R.sub.4 are identical or different and denote (C.sub.1 to C.sub.4)-alkyl, hydroxy-(C.sub.1 to C.sub.4)-alkyl, optionally (C.sub.1 to C.sub.4)-alkyl-substituted phenyl or benzyl, or, together with the nitrogen atoms to which they are bonded, an imidazolyl or a triazolyl group; and R.sub.5 denotes a benzothiazole, a benzoxazole, a benzimidazole or a cyano group. Use of the transport compound makes it possible to adjust the photosensitivity of the recording material to different spectral regions when the material is subjected to electrostatic charging of different polarities.
