PROBLEM TO BE SOLVED: To obtain a heat developable photosensitive material which gives high sensitivity and practical discrimination with decreased fog even in an easy and rapid process by forming photographic structural layers containing a specified developing agent, compds. which couple with the oxidized part of the developing agent to form dyes, and a binder, and incorporating specified two kinds of developing agents. SOLUTION: This silver halide photographic sensitive material has photographic structural layers containing photosensitive silver halides, developing agents expressed by the formula, compds. which couple with the oxidized part of the developing agents to form dyes, and a binder. The photosensitive material contains at least two kinds of developing agents having different R in the formula which represents the developing agents. In the formula, each of R1 to R4 is a hydrogen atom, halogen atom, alkyl group, alkylcarbonamide group, arylcarbonyl group, acyloxy group or the like, R is a hydrogen atom or -SO2R5, and R5 is a substd. or unsubstd. alkyl group, aryl group or heterocyclic group.
