Abstract
An electrophotographic light-sensitive medium comprising a light-sensitive layer containing a dis-azo compound represented by Formula (1) ##STR1## wherein A represents a single chemical bond, a divalent hydrocarbon group containing a conjugated double bond, a divalent hydrocarbon group containing a nitrogen atom in a conjugated double bond, or a divalent heterocyclic group which may be condensed with a benzene ring or substituted and forms a conjugated double bond system in combination with the adjacent azomethine groups, and B and B', which may be the same or different, each represents a coupler having aromatic properties.
