A developing composition for a silver halide black-and-white photographic light sensitive material comprising a compound represented by formula (1) and a compound represented by formula (2) or (3):
- ##STR7## wherein R.sub.1 and R.sub.2 are each independently a hydroxy group, mercapto group, an amino group, an acylamino group, an alkylsulfonylamino group, an arylsulfonylamino group, an alkoxycarbonylamino group, or an alkylthio group;
- Z is an atomic group necessary for forming a 5 or 6-membered ring;
- ##STR8## wherein, B is a hydrogen atom or OH;
- when B is a hydrogen atom, A.sub.1 through A.sub.9 is each independently a hydrogen atom, OH, C.sub.n H.sub.2n+1 or (CH.sub.2).sub.m X, in which n is an integer of 1 to 3, m is an integer of 0 to 3 and X is COOM.sub.1, NH.sub.2 or OH, n.sub.1 and n.sub.2 are each 1 and n.sub.3 plus n.sub.4 is an integer of 1 to 4, provided that all of A.sub.1 to A.sub.5 are not hydrogen atoms;
- when B is OH, n.sub.1 and n.sub.2 are an integer, provided that n.sub.1 plus n.sub.2 is 2, n.sub.3 is 0 and n.sub.4 is 1, A.sub.1, A.sub.8 and A.sub.9 are each a hydrogen atom, A.sub.2 through A.sub.5 are each independently a hydrogen atom, OH, COOM.sub.1, PO.sub.3 (M.sub.1).sub.2, CH.sub.2 COOM.sub.1, CH.sub.2 OH or an lower alkyl group, provided that at least one of A.sub.2 through A.sub.5 is COOM.sub.1, PO.sub.3 (M.sub.1).sub.2 or CH.sub.2 COOM.sub.1 ;
- M and M.sub.1 are each a hydrogen atom, an alkali metal atom or an ammonium group. ##STR9## wherein A.sub.10 through A.sub.13 are each COOM.sub.2 or OH;
- n.sub.5 through n.sub.8 are each an integer of 0 to 3;
- R.sub.3 through R.sub.6 are each independently a hydrogen atom, OH or a lower alkyl group;
- X is an alkylene group having 2 to 6 carbon atoms or .dbd.(B.sub.1 O).sub.m1 --B.sub.2 --, in which B.sub.1 and B.sub.2 are each an alkylene group having 1 to 5 carbon atoms and m.sub.1 is an integer of 1 to 5;
- M.sub.2 is a hydrogen atom, an alkali metal atom or an ammonium group.
