PURPOSE:To form a direct positive image having a good gradation by varying the nucleation activity per unit quantity of silver halide of the nucleating agents which act on respective layers between the layers. CONSTITUTION:The nucleation activity per unit quantity of the silver halide acting on the respective layers vary between the layers in a method for forming a direct positive image by subjecting a photographic sensitive material contg. at least two layers of internal latent image type silver halide emulsion layers which are not previously fogged to imagewise exposing, then processing the same with a surface developing soln. in the presence of the nucleating agents. The direct positive image having a good gradation balance is thereby obtd. with the photographic sensitive material formed by coating to the double layers. |
