ABSTRACT OF THE DISCLOSURE An electrophotographic recording material is disclosed comprising an electrically conductive sup- port, a photoconductive layer and, optionally, an insu- lating barrier layer between the substrate and photoconductive layer. The photoconductive layer comprises at least one organic, n-type conducting pigment in a concentration between 10 and 50, pre- ferably between 15 and 30, percent by weight, relative to the photoconductive layer weight, at least one electronically inert, carbonyl group-containing binder and an organic, p-type conducting photoconductor in a concentration from 0 to 20, preferably from 2 to 8 per- cent by weight, relative to the photoconductive layer weight. The n-type conducting pigment preferably comprises a compound selected from the trans-perinones, the perylene-tetracarboxylic acid diimides, and the condensed quinones.
