PURPOSE:To obtain a heat developable photosensitive material which is improved in processing fluctuation without degrading a raw preservable property by incorporating a prescribed non-diffusive compd. which releases a base into the heat developable photosensitive material. CONSTITUTION:At least a photosensitive silver halide, reducing agent, binder, non-diffusive dye donative material which releases or forms a diffusive dye, and the non-diffusive compd. which releases the base as a function of heat development are incorporated into the heat developable photosensitive material. The base to be released is preferably an org. base and is further preferably aliphat. amines, arom. amines, heterocyclic amines, guanidines, cyclic guanidines, amidines, cycline amidines, etc. The base releasing compd. is preferably added into the photosensitive layer. The amt. of the compd. to be added is 0.01-10g, more preferably 0.05-2g per m<2> of the heat developable photosensitive material. |
