Abstract
A photothermographic material is described which comprises a support having provided on one surface thereof at least one kind of a light-sensitive silver halide, a light-insensitive organic silver salt, a reducing agent for silver ions, and a binder, wherein the photothermographic material comprises the surface active agent represented by the following formula (F): wherein Rf represents a perfluoroalkyl group, Rc represents an alkylene group, Z represents a group having an anionic group, a cationic group, a betaine-series group, or a nonionic polar group necessary for imparting a surface activity, n represents an integer of 0 or 1, and m represents an integer of 1, 2 or 3. The photothermographic material can remarkably prevent attaching of dust, etc., which become the case of forming white spots after heat development.
