Electrophotographic recording medium
 An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are dark in color, possess substantially panchromatic absorption characteristics, and are of the general formula ##STR1## where R.sup.1 is propyl, 1-hydroxypropyl, 1-methoxypropyl or 1-phenylethyl, Z is p-phenylazoanilino, phenylthio or anilino, and n is 0-6, and a process for the production of this electrophotographic recording medium.
