Abstract

Electrophotographic recording materials which comprise an electrically conductive base, charge carrier-producing compounds (sensitizers), and compounds which are charge carrier-transporting when exposed to light, possess high photoconductivity and low conductivity in the dark, and contain, as charge carrier-transporting compounds, 1,2,3-triazoles of the fomula ##STR1## are used for reprographic purposes and for the production of electrophotographic printing plates, in particular offset printing plates.
