ABSTRACT:
A photothermographic material including, on at least one surface of a support, at least a photosensitive silver halide containing a silver iodide at 40 mol % or more, a non-photosensitive organic silver salt, and a reducing agent, wherein the photothermographic material contains two or more kinds of the reducing agent at the mixing ratio to satisfy at least one of a), b), c) and d):a) a difference between a sensitivity or b) a difference between a maximum density is 0.10 or less, when developed at 120° C. for 10 sec and a sensitivity when developed at 120° C. for 14 sec;c) a difference between a sensitivity or d) a difference between a maximum density is 0.10 or less, when developed at 117° C. for 12 sec and a sensitivity when developed at 123° C. for 12 sec.An image forming method using the photothermographic material is also provided.
