ABSTRACT:
An improved method of developing silver halide photographic light-sensitive materials comprising at least one silver halide emulsion layer on a support is disclosed. In the improvement, said silver halide emulsion layer contains core/shell type silver halide grains having a shell thickness of 25 to 150 .ANG. wherein the surface of the core is subjected to chemical sensitization treatment and the surface of the shell is not subjected to chemical sensitization, and a developing solution contains a solvent for silver halide. It is possible to carry out spectral sensitization without causing a reduction in intrinsic sensitivity and to provide high-speed silver halide light-sensitive materials which are excellent in anti-fading property of latent images and excellent in stabilization with the passage of time using the above-described improved method.
