Abstract
A color image-forming process is disclosed, which comprises imagewise exposing a silver halide photographic material comprising a reflective support having provided thereon at least one light-sensitive silver halide emulsion layer constituted by at least two kinds of monodispersed silver halide grains containing substantially no silver iodide and substantially deffering from each other in mean grain size, and developing the exposed photographic material for a developing time of within 2 minutes and 30 seconds using a color developer containing substantially no benzyl alcohol.

A color image-forming process which comprises imagewise exposing a silver halide photographic material comprising a reflective support having provided thereon at least one light-sensitive silver halide emulsion layer constituted by at least two kinds of monodispersed silver halide grains which are free of silver iodide and substantially differ from each other in mean grain size, and developing the exposed photographic material for a developing time of within 2 minutes and 30 seconds using a color developer containing substantially no benzyl alcohol, wherein the two kinds of monodispersed silver halide grains which are respectively the most and the second most by weight, among said at least two kinds of monodispersed silver halide grains, satisfy the conditions of
- 1.2.ltoreq.(.gamma..sub.1 /.gamma..sub.2).sup.2 .ltoreq.4.0,
- wherein .gamma..sub.1 represents the mean grain size of the larger kind of grains, and .gamma..sub.2 represents the mean grain size of the smaller kinds of grains, and wherein the monodispersed silver halide grains form a latent image predominantly on the surface thereof upon exposure to light.
