ABSTRACT:
An electrophotographic recording material comprising a conductive support and a photosensitive layer containing a photoconductive compound that has p-type charge generating capacity and is a trisazo compound which is the reaction product of the coupling reaction between a coupler compound that does not contain a carboxylic acid or sulphonic acid group and a diazonium salt represented by the following general formula (I): ##STR1## wherein: each of L, M and Y (same or different) represents a phenylene group including a phenylene groups substituted with one or more substituents selected from the group consisting of lower alkyl (C.sub.1 -C.sub.2), nitro, methoxy, ethoxy or halogen, or represents said phenylene group fused-on with the necessary atoms to close a saturated or unsaturated carbocyclic or heterocyclic ring or ring system including said ring or ring-system in substituted form, and X.sup.- is an anion.
