Heat developable image recording material

A heat developable photosensitive material comprising a photosensitive silver halide, a reducing agent for silver ions, a binder and non-photosensitive organic silver salt particles on one side of the surface of a substrate, wherein a content of silver behenate in the non-photosensitive organic silver salt particles is 90 mol % to 100 mol %, the photosensitive material comprising a compound represented by the following general formula (3):

• 55
• wherein, in the general formula (3), R21, R22 and R23 each independently represent a substituted or non-substituted alkyl group, aryl group, alkoxy group, aryloxy group, amino group or heterocyclic group;
• and, when any of the substituent when any of R21, R22 and R23 have a substituent, the substituent comprises a halogen atom, an alkyl group, an aryl group, an alkoxy group, an amino group, an acyl group, an acyloxy group, an alkylthio group, an arylthio group, a sulfonamide group, an acyloxy group, an oxycarbonyl group, a carbamoyl group, a sulfamoyl group, a sulfonyl group or a phosphoryl group.

A heat developable photosensitive material comprising a photosensitive silver halide, a reducing agent for silver ions, a binder and non-photosensitive organic silver salt particles on one side of the surface of a substrate, wherein the non-photosensitive organic silver salt particles are prepared from organic acids including at least behenic acid and erucic acid, and a content of the erucic acid is 0.000001 mol % to 0.4 mol % relative to the behenic acid.
