A heat developable light-sensitive material capable of giving images of high density and less fog in a short period of time, and which is excellent in stability. The heat developable light-sensitive material comprises a support and is formed thereon a heat developable light-sensitive layer, wherein said light-sensitive material contains at least one compound selected from the group consisting of compounds represented by formula (I) or (II) as a base precursor:
wherein R represents 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 or a heterocyclic group; X represents a substituent; P represents an integer of 0 to 4; B represents a monoacidic base or diacidic base; M represents an alkali metal or an alkaline earth metal; and m represents 1 when B represents monoacidic base and represents 2 when B represents diacidic base, and m' represents the valence number of M.
