There is provided a silver halide photographic photosensitive material, containing a support and at least one photosensitive silver halide emulsion layer on the support, the silver halide photographic photosensitive material, further including at least one layer containing an emulsion having at least one surfactant represented by the formula (I), in which the photosensitive material contains a substantially non-color-forming photosensitive emulsion layer. The formula (I) is indicated as (R1—L)n-J-(A)m. In the formula: A represents an acid group or a metal salt thereof; R1represents an aliphatic group; L represents a divalent group; J represents a linking group, having a valence of n plus m, which links R1—L and A; n represents a natural number of from 1 to 6; and m represents a natural number of from 1 to 3.
