Silver halide photosensitive material for color-photography and image information method using the same

An image forming method comprising the steps of:

• exposing a silver halide color photosensitive material;
• beginning to subject the exposed silver halide color photosensitive material to a color development within nine seconds of the exposure;
• and
• completing the color development within 28 seconds,
• wherein the silver halide color photosensitive material comprises:
• a support;
• and
• a photograph constitution layer provided on the support, and including at least one layer that comprises a yellow dye-forming coupler, at least one layer that comprises a magenta dye-forming coupler, at least one layer that comprises a cyan dye-forming coupler, and at least one non-photosensitive hydrophilic colloid layer,
• wherein the coupler-comprising layers respectively include silver halide emulsions, and at least one of the silver halide emulsions has a silver halide content of 90 mol % or more;
• and
• and wherein an average spherical equivalent diameter of the silver halide particles in the silver halide emulsion layer that contains the yellow dye-forming coupler is from 0.30 μm to 0.70 μm.
