Abstract:
A method for processing a silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer, comprising processing with a developing solution which contains a six-membered heterocyclic compound having two nitrogen atoms as the constituent atoms of the six-membered ring and a mercapto group, a hydroxyl group and at least one substituent group other than a hydrogen atom and a five-membered heterocyclic compound having two to three nitrogen atoms as the constituent atoms of the five-membered ring and at least one mercapto group, wherein said six-membered heterocyclic compound is a compound represented by the following general formula (I) and said five-membered heterocyclic compound is a compound represented by the following general formula (II): ##STR75## wherein, one of R.sup.1 and R.sup.2 represents an alkyl group having from 1 to 10 carbon atoms which may be substituted or unsubstituted, an aryl group having from 6 to 12 carbon atoms, an aralkyl group having from 7 to 12 carbon atoms, a nitro group, a cyano group or a halogen atom, provided that when R.sup.2 is an alkyl group, the alkyl group is unsubstituted; and the sum total of carbon atoms in R.sup.1 and R.sup.2 is from 2 to 20; or R.sup.1 and R.sup.2 may be combined together to form a five-membered or six-membered ring; ##STR76## wherein X and Y each represents a nitrogen atom or CR.sub.3 ; Z represents NR.sub.4 ; X and Y may be combined together to form a condensed ring; R.sub.3 and R.sub.4 each represents a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, a hydroxyl group, a nlercapto group, a carboxyl group, a sulfo group, a phosphono group, an amino group, a nitro group, a cyano group, a halogen atom, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, a sulfamoyl group or an alkoxy group; and M represents a hydrogen atom, an alkali metal atom, a quatemary amnionium or a quaterny phosphonium, andwherein both of the compounds of formulae (I) and (II) are used in an amount of from 0.01 to 100 mmol per liter.
