ABSTRACT:
A method for forming an image which comprises developing an imagewise exposed 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 contains a silver chlorobromide emulsion having an average silver bromide content of from 0.1 to 10 mol % and containing substantially no iodide in at least one layer thereof, at least said silver chlorobromide emulsion containing a gold compound, and said color developer contains from 3.5.times.10.sup.-2 to 1.5.times.10.sup.-1 mol/l of chloride ion and from 3.0.times.10.sup.-5 to 1.0.times.10.sup.-3 mol/l of bromide ion. According to the method, streaky pressure marks accompanying processing with an automatic developing machine and variations in photographic characteristics, particularly of gradation in low density areas, accompanying continuous processing can be prevented without decreasing the maximum density and, a residual silver amount can be markedly reduced.
