ABSTRACT:
A method for processing a silver halide photographic material which comprises processing an imagewise exposed silver halide photographic material with a processing solution having a fixing ability containing (1) a thiosulfate As disclosed, wherein said processing solution having a fixing ability further contains at least one of (2) at least one compound selected from the group consisting of a bisulfite and a sulfite, and a compound represented by formula (A'): ##STR1## wherein R'.sub.1, R'.sub.2, R'.sub.3, R'.sub.4 and R'.sub.5 each represents a hydrogen atom or a substituent other than a hydroxyl group or a group containing a hydroxyl group, provided that at least one of R'.sub.1 to R'.sub.5 is at least one of a sulfo group and a group constaining a sulfo group and (3) at least one bisulfite addition product of a compound represented by formula (A'). In the method, a fixing solution having a pH of from 5.0 to 9.0 or a bleach-fixing solution with improved stability over time during continuous processing and exhibiting excellent desilvering performance is used. The method provides an image showing a reduced increase in stain with time and realizes improvements of the working environment.
