Heat developable photosensitive material

A heat developable photosensitive material comprising at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for silver ions and a binder on one surface of a support,

• wherein the non-photosensitive organic silver salt contains 53 mol % to 85 mol % of silver behenate;
• and the total amount of silver of the non-photosensitive organic silver salt and photosensitive silver halide is 0.1 to 1.9 g/m2;
• and the reducing agent includes at least one of polyphenol compounds represented by the following formula (1):
• and any layer that is provided on a support side with the photosensitive silver halide contains an aromatic carboxylic acid compound represented by the following formula (2):
• wherein in formula (1), each of R11 and R11′ represents a t-butyl group, each of X11′ and R12′ independently represents a hydrogen atom or group that can bond to a first benzene ring of the polyphenol compounds, and each of X11 and R12 independently represents a hydrogen atom or group that can bond to a second benzene ring of the polyphenol compounds;
• and R11 and X11, R11′ and X11′, R12 and X11, and R12′ and X11′, respectively, may bond to each other to form a ring;
• and L represents a —S— group or a —CHR13— group;
• and R13 represents a hydrogen atom or an alkyl group;
• wherein in formula (2), each of R1 to R5 independently represents a hydrogen atom or group that can bond to a benzene ring;
• at least one of R1 to R5 represents a non-dissociating substituent that bonds to the benzene ring via a carbon atom, nitrogen atom, oxygen atom, sulfur atom or phosphorous atom;
• R1 or R5 represents an arylsulfonyloxy group;
• and R1 to R5 are not a carboxyl group or group having a carboxyl group;
• and
• wherein the amount of the at least one of polyphenol compounds is 0.2 to 1.8 g/m2.
