PURPOSE:To rapidly and stably form a direct positive image by imagewise exposing a photosensitive material having an internal latent image type photographic silver halide emulsion layer for direct positive on the support, subjecting the material to fogging exposure before or during development and developing it in the presence of a specified compd. CONSTITUTION:A photosensitive material having an internal latent image type photographic silver halide emulsion layer for direct positive on the support is imagewise exposed and subjected to fogging exposure before or during development and the material is developed in the presence of a compd. represented by the formula. In the formula, M is H, an alkali metal atom, ammonium or a group which cleaves under alkali conditions, X is (, S or Se, and each of R5-R8 is H, optionally substd. alkyl or the like. A light source emitting light within the photosensitive wavelength range of the photosensitive material may be used as a light source for the fogging exposure and a fluorescent lamp, a tungsten lamp, a xenon lamp or sunbeams are generally used. Thus, a direct positive color image hardly undergoing deterioration by air oxidation and having stable performance over a long period can be formed. |
