A silver halide photographic material is described, which comprises a support having provided thereon at least one light-sensitive silver halide emulsion layer and at least one light-insensitive hydrophilic colloid layer, wherein the at least one light-sensitive silver halide emulsion layer contains at least two kinds of silver halide emulsions having different speeds, the light-insensitive hydrophilic colloid layer contains at least one kind of light-insensitive silver halide grains, the silver halide emulsion layer or the light-insensitive hydrophilic colloid layer contains at least one kind of hydrazine derivative as a nucleating agent, and at least one kind of compound selected from the group consisting of an amine derivative, an onium salt, a disulfide derivative and a hydroxymethyl derivative as a nucleation accelerator. A method for processing the silver halide photographic material is also described.
