- 1 - ABSTRACT OF THE DISCLOSURE An electrophotographic recording material comprising a photoconductive layer incorporating photoconductive zinc oxide in the presence of a compound within the scope of the following general formula : R - SH wherein : R represents (1) an unsubstituted aliphatic hydrocarbon group containing at least 5 carbon atoms or (2) an aliphatic hydrocarbon group substituted with a -COOQ group wherein Q is an organometallic group or an ali- phatic hydrocarbon group, containing at least 5 carbon atoms, or (3) an aliphatic hydrocarbon group substituted with a -COOH group and containing at least two methylene groups between the -COOH group and the -SH group, and said general formula including the modification wherein the hydrogen atom of the -SH group is substituted to form an organometal mercaptide. The above compound improves the charge retention of the photoconductive layer, i.e. lowers its dark-decay, under conditions of high relative humidity.
