Development processing method

A development processing method which comprises:

• exposing a silver halide light sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer;
• and
• developing said exposed light-sensitive material with a developing solution,
• wherein at least one of said silver halide emulsion layer and other hydrophilic colloidal layers contains 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 derivative developing agent, (2) at least one aminophenol auxiliary developing agent and (3) a compound represented by formula (I):
• ##STR128## wherein R.sub.1 to R.sub.4, which may be the same or different, each represents a hydrogen atom, a halogen atom or a substituent group bonded to the ring in formula (I) with a carbon atom, a nitrogen atom, an oxygen atom, a sulfur atom or a phosphorus atom contained in the substituent, with the proviso that R.sub.1 and R.sub.3 each does not represent a hydroxyl group, 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 R.sub.1 and R.sub.2 in formula (I) are not connected to each other to form a ring;
• and
• wherein the compound represented by formula (I) is present in an amount of from 0.1 to 5 mmol per liter of the developing solution.
