There is provided a method for forming an image, which comprises processing a silver halide color photographic material that has a high-silver-chloride silver halide emulsion and which contains in the photographic material a nitrogen-containing heterocyclic compound, the solubility product of which for the silver salt is in a limited range, with a color developer containing chloride ions and bromide ions in a limited concentration, respectively. The method is excellent in forming an image that can be performed rapidly, and is high in sensitivity, in prevention of processing color-mixing, and in less fluctuation of the photographic quality involved in continuous processing. |

DETAILED DESCRIPTION OF THE INVENTION In accordance with the present invention there is provided a method for processing a silver halide color photographic material that has silver halide emulsion layers, at least one of which has a high-silver-chloride silver halide emulsion comprising 80 mol % or over of silver chloride, and which contains in said photographic material a nitrogen-containing heterocyclic compound, the solubility product of the silver salt of which is 10.

The color photographic material of the present invention can be constituted by applying at least each of a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer on a base.
For common color print papers, the above silver halide emulsion layers are applied in the above-stated order on the base, but the order may be changed.
Color reproduction by the subtractive color process can be performed by incorporating; into these photosensitive emulsion layers, silver halide emulsions sensitive to respective wavelength ranges, and so-called couplers capable of forming dyes complementary to light to which the couplers are respectively sensitive, that is, capable of forming yellow complementary to blue, magenta complementary to green, and cyan complementary to red.
However, the constitution may be such that the photosensitive layers and the color formed from the couplers do not have the above relationship.
As the silver halide emulsion used in the present invention, one substantially free from silver iodide and having a silver chloride content of 80 mol % or over, based on the total silver halide, can be preferably used.
Herein the term "substantially free from silver iodide" means that the silver iodide content is 1 mol % or below, and preferably 0
