ABSTRACT:
A method for forming an image, which comprises developing a silver halide color photographic material with a color developer containing at least one aromatic primary amine color developing agent, wherein said silver halide color photographic material comprises a silver chloride or silver chlorobromide emulsion having an average silver bromide content of not more than 10 mol % and containing substantially no iodide, with a mean grain size of an emulsion contained in the blue-sensitive layer thereof being controlled to 0.9 .mu.m or smaller, silver halide to coupler ratio in said blue-sensitive layer ranges from 2 to 5 as a molar ratio, and said color developer contains from 3.5.times.10.sup.-2 to 1.5.times.10.sup.-1 mol/l of a chloride ion and from 3.0.times.10.sup.-5 to 1.0.times.10.sup.-3 mol/l of a bromide ion. The method achieves rapid processing to provide an image having high maximum density and low density without causing streaky pressure marks even when processing is carried out with an automatic developing machine or without a variation of photographic characteristics, particularly gradation in low density areas, occurring even when processing is carried out continuously.
