A heat-developable light-sensitive material is described, containing a compound represented by formula (I) ##STR1## wherein R.sub.1 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted alkylene group, a substituted or unsubstituted cycloalkylene group, a substituted or unsubstituted alkenylene group, a substituted or unsubstituted alkynylene group, a substituted or unsubstituted aralkylene group, a substituted or unsubstituted arylene group, or a substituted or unsubstituted divalent heterocyclic group; R.sub.2 represents a hydrogen atom, a substituted or unsubstituted alkyl group; R.sub.3 represents an alkyl group, an alkoxyl group, a halogen atom, an acylamino group, a sulfonylamino group, an alkylamino group, a dialkylamino group, an alkylsulfonyl group, an arylsulfonyl group, a cyano group, a substituted or unsubstituted carbamoyl group, a substituted or unsubstituted sulfamoyl group or an alkoxycarbonyl group; X represents a divalent group selected from ##STR2## (wherein R.sub.4 represents a hydrogen atom, a substituted or unsubstituted alkyl group), ##STR3## (wherein R.sub.5 represents a substituted or unsubstituted alkyl group), and ##STR4## M represents an alkali metal, an alkaline earth metal, a quaternary ammonium group, or an ammonium group represented by BH (wherein B represents an organic base); l is an integer of 0 to 3; and m and n are each an integer of 1 or 2, such that the electric charge of carboxylate anion is equivalent to that of M. This material is improved in activity and storage stability. That is, the material providing an image of high density and decreased fog, and which even when stored under high temperature/high humidity conditions, maintained good photographic performance.
