PROBLEM TO BE SOLVED: To provide a black and white heat developable photosensitive material having low fog and high image density, excellent in image tone, and excellent also in image storage stability, and an image forming method. SOLUTION: The heat developable photosensitive material contains on a support at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for silver ions and a binder, wherein the reducing agent contains a reducing agent represented by formula (1), wherein R<SB>1</SB>-R<SB>4</SB>each independently represent H or a substituent substitutable on the benzene ring; and R<SB>5</SB>represents an alkyl group, an aryl group or a heterocyclic group having at least one basic group.
