A photothermographic material comprising, on a support, an image forming
layer containing at least a photosensitive silver halide, a
non-photosensitive organic silver salt, a reducing agent and a binder,
and a non-photosensitive outermost layer at a surface side of the support
at which the image forming layer is provided, wherein: 1) the
non-photosensitive organic silver salt contains 90% by mole or more of
silver behenate; and a binder in the outermost layer contains 50% by
weight or more of a hydrophobic polymer latex, 2) the outermost layer
contains a polymer latex; and a layer adjacent to the outermost layer
contains a binder which can lose fluidity upon a decrease in temperature,
or 3) the outermost layer contains a polymer latex; and a coating
solution for forming the outermost layer can lose fluidity upon a
decrease in temperature.
