Abstract:
A method of developing a photothermographic material comprising the steps of:exposing a photothermographic material to light, and heat-developing the photothermographic material by the use of an automatic thermal processor, wherein the photothermographic material comprises a support, a light-sensitive silver halide, an organic silver salt, a reducing agent and a contrast-increasing agent, and wherein in the step of heat-developing, the photothermographic material is transported at a speed of 22 to 40 mm/sec,; the photothermographic material is subjected to heat development at a temperature of not less than 117Â° C. in not less than 10 sec., and then the photothermographic material is brought into contact with the surface of a heating member exhibiting a surface temperature of 90 to 115Â° C.
