Process for forming super high contrast negative images

A process for forming super high contrast negative images, which comprises processing a super high contrast negative type silver halide photographic material comprising a support having thereon at least one layer, one of which must be a silver halide emulsion layer, said silver halide emulsion layer or other hydrophilic colloid layer containing at least one hydrazine derivative represented by formula (IX)

• R.sub.21 --NHNH--CHO (IX)
• where R.sub.21 represents an aliphatic group or an aromatic group and at least one nucleation accelerator represented by the following formula (Ia) with a developer having a pH of from 9.6 to 11.0;
• Y[(A.sub.1 --.sub.p A.sub.2 --B].sub.m (Ia)
• wherein Y represents a group adsorbing onto silver halide;
• A.sub.1 represents a divalent linkage group composed of an atom or an atomic group selected from hydrogen, carbon, nitrogen, oxygen, and sulfur and selected from ##STR14## or a combination thereof with a straight chain or branched alkylene group wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9 and R.sub.10 each represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkenyl group or a substituted or unsubstituted aralkyl group;
• A.sub.2 represents a divalent linkage group selected from a straight chain or branched alkylene group, a straight chain or branched alkenylene group, a straight chain or branched aralkylene group or a straight chain or branched arylene group;
• B represents a substituted or unsubstituted amino group, an ammonium group, or a nitrogen-containing heterocyclic ring;
• m represents the integer 1, 2, or 3;
• and p represents 0 or the integer 1,
• wherein said nucleation accelerator of formula (Ia) is present in an amount of from 5 mg/m.sup.2 to 500 mg/m.sup.2 in said photographic material, and
• wherein said hydrazine derivative is present in an amount of from 1 mg/m.sup.2 to 300 mg/m.sup.2 in said photographic material.
