A superhigh contrast negative type silver halide photographic material comprising a support having provided thereon at least one silver halide emulsion layer, the emulsion layer or at least one other hydrophilic colloid layer containing at least one hydrazine derivative and at least one compound of formula (I): Y[(X)nA-B]m (I) wherein Y represents a group capable of adsorbing to silver halide; X represents a divalent linking group comprising an atom or atoms selected from a hydrogen atom, a carbon atom, a nitrogen atom, an oxygen atom and a sulfur atom or an atomic group comprised of the atoms; A represents a divalent linking group; B represents a substituted or unsubstituted amino group, an ammonium group or a nitrogen-containing heterocyclic group; m represents 1, 2 or 3; and n represents 0 or 1. The photographic material may contain an organic desensitizer and a water-soluble rhodium salt, and the material has a low sensitivity and can be handled in a bright room. |
