Abstract: A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support base having positioned thereon a silver halide emulsion layer and a protective layer. The silver halide emulsion layer includes at least two component layers including an upper layer and a lower layer. The upper layer is comprised of a photosensitive silver halide emulsion and the lower layer is comprised of a photosensitive silver halide emulsion and an inside fogged silver halide emulsion. The particle size of the inside fogged silver halide emulsion is smaller than that of the photosensitive silver halide emulsion in the upper layer and the lower layer. The material is highly sensitive and forms images which have high contrast and high density. The material is capable of forming images having a pure black tone. When the materials are processed they create substantially no stain even if a stopping bath is not utilized.
