ABSTRACT:
The present invention provides a method for forming color images by processing in a short period of time color photographic materials containing at least one oil-soluble coupler with a color developer which does not substantially contain benzyl alcohol, wherein a silver halide color photographic material having at least one silver halide emulsion layer on a reflective support, the emulsion layer containing a dispersion of oleophilic fine grains having a mean grain size of 0.25 .mu.m or less, which contain a coupler capable of forming a dye after having been coupled with an oxidation product of an aromatic primary amine developing agent, and at least one high boiling organic solvent having a dielectric constant of 4.00 or more (25.degree. C., 10 KHz). The photographic material is imagewise exposed and then subjected to development with a color developer which contains an aromatic primary amine developing agent but does not substantially contain benzyl alcohol for 2 minutes and 30 seconds or less.
