Development processing method

A development processing method which comprises the steps of:

• imagewise exposing a silver halide photographic light-sensitive material;
• and
• developing the exposed photographic material with a developing solution,
• wherein the silver halide photographic material comprises a support having thereon at least one light-sensitive silver halide emulsion layer, at least one of said silver halide emulsion layer and other hydrophilic colloidal layers containing at least one hydrazine derivative;
• and
• wherein said developing solution is substantially free from a dihydroxybenzene compound, has a pH of from 9.0 to 10.5 and contains (1) at least one ascorbic acid developing agent, (2) at least one 1-phenyl-3-pyrazolidone auxiliary developing agent and (3) a compound represented by the following formula (I):
• ##STR75## wherein R.sub.1 to R.sub.4 may be the same or different and each represents a hydrogen atom, a halogen atom or a substituent group bonded to the ring in formula (I) by a carbon atom, a nitrogen atom, an oxygen atom, a sulfur atom or a phosphorus atom, with the proviso that neither R.sub.1 nor R.sub.3 represents a hydroxyl group, that R.sub.1 and R.sub.2 in formula (I) are not connected to each other to form a ring, and that at least two of R.sub.1 to R.sub.4 are --SM groups, wherein M represents a hydrogen atom, an alkali metal atom or an ammonium group,
• wherein the compound represented by formula (I) is present in an amount of 0.1 to 5 mmol per liter of the developing solution.
