As the diffusion transfer type heat developable photosensitive material used in the present invention, a positive type diffusion transfer type heat developable color photosensitive material is preferably used. Specific examples of these include, for example, Japanese Patent Application Laid-Open No. 59-12
No. 4327, No. 59-1524404, No. 59-154
It is described in various publications such as No. 445 and the specification of Japanese Patent Application No. 58-42779. Typical examples of such heat-developable photosensitive materials include, for example, photosensitive tin halide (which may contain an organic silver salt), an electron donor, an electron transfer agent, and a material that is reduced at high temperatures to release a heat transferable dye. A photosensitive material containing a dye-providing substance or the like, or a photosensitive silver halide (preferably containing an organic silver salt), is oxidized by the photosensitive silver halide and/or organic silver salt in the exposed area under high temperature conditions and is thermally transferred. These are photosensitive materials that contain dye-donating substances that no longer emit colorants. Such a heat-developable photosensitive material uses ordinary negative silver halide, and provides a silver image in a negative-positive relationship and a heat-transferable dye image in a positive-positive relationship to an original by simply performing thermal development after image exposure.
