Abstract
A method for forming a color image which comprises imagewise exposing a color photographic material comprising a reflective support having thereon at least one photosensitive layer containing a color coupler capable of forming a dye image through its coupling reaction with an oxidation product of an aromatic primary amine color developing agent and a silver halide emulsion and processing it with a color developing solution containing substantially no benzyl alcohol, wherein the color development is carried out under the condition that a substantially colorless anionic surface active agent having an unsubstituted aliphatic group, a substituted aliphatic group excluding a fluorine-substituted aliphatic group, or an unsubstituted or substituted aromatic group as a hydrophobic group; and --SO.sub.3 M, --SO.sub.2 M, --OSO.sub.3 M, or --OSO.sub.2 M, wherein M represents a hydrogen atom or a metallic atom or atomic group capable of being a cation, as a hydrophilic group in the molecule thereof is present in the photosensitive layer in an amount within a range of from 0.1 to 3 times the total weight of the color couplers applied in the photosensitive layer during the color development.
