ABSTRACT:
A method for processing an exposed black and white silver halide photographic light-sensitive material includes the steps of: (1) developing the exposed light-sensitive material with a developing solution, (2) fixing the developed material with a fixing solution, (3) washing the fixed material with water which is replenished in an amount of from 0 to 3 liter/m.sup.2 of the exposed light-sensitive material, and (4) drying the washed material. The developing solution is replenished with a solid photographic composition. This solid photographic composition includes a developing agent selected from the group of a dihydroxybenzene developing agent represented by Formula I and a developing agent represented by Formula II (provided that the developing agent represented by Formula II may form a sodium salt, a potassium salt or a lithium salt). Formulae I and II are as follows: ##STR1## In the formulae, R.sub.1, R.sub.2, R.sub.3, and R.sub.4 each represents a hydrogen atom, an alkyl group, an aryl group, a carboxyl group, a halogen atom or a sulfo group; R.sub.7 represents a hydrogen atom, an alkyl group, an aryl group, an amino group, an alkoxyl group, a sulfo group, a carboxyl group, an amido group or a sulfonamido group; E.sup.1 represents an oxygen atom or a sulfur atom; and E.sup.2 represents an oxygen atom, a sulfur atom or an NR.sub.8 group, provided that R.sup.8 represents an alkyl group or an aryl group.
