摘要： A silver halide color photographic light-sensitive material has a support and at least one silver halide emulsion layer. At least one of the silver halide emulsion layers has a group of substantially monodisperse core/shell type silver halide grains having a value of not greater than 0.15. This value is obtained by dividing a standard deviation value by the average grain size value. The substantially monodisperse core/shell-type silver halide grains have shells from 0.01 to 0.1 in thickness. The silver halide grains include a silver iodide in the core in an amount of less than 8 mole % and a silver iodide in the shell of from 0.1 mole % to 6 mole %. A development inhibitor releasing compound having a relative development inhibitability of not less than 1 is also present in the emulsion layer.

摘要： A method for forming photographic color images is disecond closed, in which a silver halide color photographic light-sensitive material is rapidly processed with low replenishment of processing solutions. The images improved in lowered yellow stain can be obtained. The processing comprises steps of color developing, bleaching immediately after the developing step, and treating with a bath having a fixing capability following the bleaching step. The steps of bleaching and treating with a solution having a fixing capability are carried out for a time of not more than 3 minutes 45 seconds at a temperature of from 20.degree. to 45.degree. C. The light-sensitive material comprises silver halide emulsion layers each containing silver bromide and/or silver boromoiodide grains and satsifies at least one of the following requirements (1) and (2); (1) a blue light-sensitive emulsion layer included in the silver halide emulsion layers has a silver density d of not less than 4.0.times.10.sup.-1 g/cm.sup.3. (2) a green light-sensitive emulsion layer included in the silver halide emulsion layers has a silver density d of not less than 6.0.times.10.sup.-1 g/cm.sup.3.
