Abstract (en)

A silver halide photographic material comprising a support having tehreon at least one silver halide emulsion layer composed of one or more layers, wherein the silver halide emulsion contained in at least one layer of the silver halide emulsion layer is chemically sensitized so that silver halide grains in the emulsion have at least one maximum value of the latent image number in distribution thereof in the inside of the silver halide grains and the position where the maximum value(s) exists is at a depth of less than 0.01 mu m from the surface of the grains, and the emulsion also has a latent image number of at least 1/5 of the largest maximum value but less than the largest maximum value on the surface of the grains.
