Abstract:
A development processing method comprising a step of developing a silver halide photographic material having at least one silver halide emulsion layer with a developing solution containing a hydroquinone developing agent,wherein said developing solution has a pH of from 9.0 to 11.0, and contains a compound represented by formula (A) or (B) in an amount of at least 0.1 mmol per liter thereof and a compound represented by formula (II) in a concentration ratio of the compound represented by formula (II)/the hydroquinone developing agent of from 0.03 to 0.12: ##STR18## wherein in formula (A), R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents a hydrogen atom, a halogen atom or a substituent which is bonded to the ring in formula (A) by a carbon atom, a nitrogen atom, an oxygen atom, a sulfur atom or a phosphorus atom contained in the substituent, provided that at least two of R.sub.1 to R.sub.4 represent an --SM group, wherein M represents a hydrogen atom, an alkali metal atom or an ammonium group;wherein in formula (B), R.sub.5, R.sub.6, and R.sub.7 each represents a hydrogen atom, a halogen atom or a substituent which is bonded to the ring in formula (B) by a carbon atom, a nitrogen atom, an oxygen atom, a sulfur atom or a phosphorus atom contained in the substituent, provided that at least two of R.sub.5 to R.sub.7 represent an --SM group, wherein M represents a hydrogen atom, an alkali metal atom or an ammonium group; ##STR19## wherein in formula (II), R.sub.1 and R.sub.2 each represents a hydroxyl group, an amino group, an acylamino group, an alkylsulfonylamino group, an arylsulfonylamino group, an alkoxycarbonylamino group, a mercapto group or an alkylthio group; and X comprises at least one of a carbon atom, an oxygen atom and a nitrogen atom and forms a 5- or 6-membered ring together with the two vinyl carbons on which R.sub.1 and R.sub.2 are substituted and the carbonyl carbon.
