A heat developable light-sensitive material is disclosed. The material comprises a support having provided thereon at least a light-sensitive silver halide, a reducing agent, a binder and an organic silver salt of the formula: <IMAGE> (I) wherein R1 represents a hydrogen atom or a substituted or unsubstituted alkyl, cycloalkyl, alkenyl, alkynyl, aralkyl, aryl or heterocyclic group; R2 represents a hydrogen atom or a substituted or unsubstituted alkyl group; R3 represents a halogen atom, a substituted or unsubstituted alkyl, alkoxy, amino, alkylsulfonyl, arylsulfonyl, carbamoyl, sulfamoyl or alkoxycarbonyl group or a cyano group; X represents <IMAGE> wherein R4 represents a hydrogen atom or a substituted or unsubstituted alkyl group, -SO2 -, <IMAGE> wherein R5 represents a substituted or unsubstituted alkyl group, and <IMAGE> and l represents 0 or an integer of from 1 to 3; and when l is 2 or 3, the group R3 may be the same or different. The material provides an image of high density with less fog in a short time even using a reduced amount of a base precursor.
