A silver halide photographic material is disclosed, which has high image quality in addition to high sensitivity. The photographic material comprises a support and at least one silver halide light-sensitive emulsion layer containing a compound being capable of splitting off a diffusible development-inhibitor or a precursor thereof upon a reaction with an oxidized product of a color developing agent. At least one of the silver halide light-sensitive emulsion layer layer and a layer adjacent to the light-sensitive emulsion layer contains a silver halide emulsion comprising a silver halide grain having an internal fog nucleus.
