PROBLEM TO BE SOLVED: To suppress heat developing fog and fog due to storage and improve the deterioration of image density by including a specific compound and including one kind of compound selected from the other specific compound, an aziridine compound, an epoxy compound and a carboxyimide compound. SOLUTION: The heat-developable photosensitive material contains at least one kind of compound selected from formula I and the like and at least one of compounds selected from ones represented by formula II and the like, and aziridine compounds, epoxy compounds, and carboxyimide compounds. In formula I, each of Hal1 and Hal2 is a halogen atom; X1 is an anion; R1 is a group having a carbonyl group as a partial structure; each of R2 and R3 is an H atom or a group substitutible on an N atom; and (n) is 1 or 2, and in formula II, each of R1-R3 is, independently, an alkyl or aralkyl group or the like; and X- is a counter ion and when a sulfonyl group is present in the molecule, X- is absent.
