Method for processing silver halide photographic light-sensitive material

A method of processing a black and white silver halide photographic light sensitive material, using an automatic developing machine, the method comprising the steps of:

• exposing the material;
• and
• developing the exposed material with developer, the developer being replenished with developer replenisher and the developer containing 0.05 to 0.5 mol/liter of a developing agent represented by Formula (A-a):
• ##STR54## wherein R.sub.7 represents a hydrogen atom, an alkyl group, an aryl group, an amino group, an alkoxy group, a sulfo group, a carboxy group, an amido group or a sulfonamido group;
• M.sub.1 and M.sub.2 independently represent a hydrogen atom or an alkali metal atom;
• Y.sub.1 represents O or S;
• and Y.sub.2 represents O, S or NR.sub.8 in which R.sub.8 represents a hydrogen atom, an alkyl group or an aryl group, wherein the method satisfies the following inequality:
• 1. 1.ltoreq.D.sub.R /D.sub.S .ltoreq.2.5
• in which D.sub.S represents the developing agent concentration of a fresh developer and D.sub.R represents the developing agent concentration of a running developer in stationary state.
