Abstract

Abstract A method of forming colored images by exposing and then developing a silver halide color photographic photosensitive material which has a blue sensitive silver halide emulsion layer, a green sensitive silver halide emulsion layer and a red sensitive silver halide emulsion layer on a support. In the method, silver halide grains which have a silver bromide containing phase of which the silver bromide content is from 10 to 60 mol % localized at the surface or within the grains, and in which from 95 to 99.5 mol % (average value) of the grains as a whole in the emulsion layer consists of silver chloride, the remainder consisting of substantially silver iodide free silver bromide, are included in at least one of the green sensitive and red sensitive silver halide emulsion layers. The material is subjected to a scanning exposure with blue light, green light and red light.
