摘要： Disclosed are an image formation process which comprises developing a photographic material comprising a silver halide emulsion layer, and a hydrazine derivative and a specific phosphonium compound of formula (1) with a developer which is substantially free of a dihydroxybenzene developing agent, contains a specific developing agent of formula (2) and at least one p-aminophenol derivative, and has a pH value of not more than 10, and a development process which comprises developing a photographic material comprising a silver halide emulsion layer, and a hydrazine derivative and a nucleation accelerator, with a developer having a pH value of from 9.0 to 10.5 and containing a first developing agent selected from ascorbic acid and a derivative thereof and a second developing agent selected from aminophenol and a derivative thereof, wherein a solution having the same composition as the fresh developer but a higher pH value than the fresh developer is used as a development replenisher. The image formation process enables the formation of a high contrast image desirable in the field of graphic arts with a stable developer which is unharmful to an ecosystem or working atmosphere and shows an extremely small deterioration with time, and the development process is useful for a plate-making silver halide photographic material, accomplishes an ultrahigh contrast, minimizes the pH variation during running processing, and reduces the burden on environment.
