A silver halide photographic material comprising a hydrazine derivative represented by the following formula (I) and a surface active compound represented by the following formula (II):
- ##STR27## wherein R.sub.1 represents an aliphatic group or an aromatic group;
- R.sub.2 represents a hydrogen atom, an alkyl group, an aryl group, an unsaturated heterocyclic group, an alkoxy group, an aryloxy group, an amino group or a hydrazino group;
- G.sub.1 represents --CO--, --SO.sub.2, --SO--, --PO(R.sub.3)-- or --CO--CO--, a thiocarbonyl group or an iminomethylene group, in which R.sub.3 has the same meaning as R.sub.2 ;
- A.sub.1 and A.sub.2 are both a hydrogen atom, or one of them is a hydrogen atom and the other is an alkylsulfonyl group, an arylsulfonyl group, or an acyl group;
- ##STR28## wherein R.sub.4 represents an aliphatic group, an alicyclic group, an aromatic group or a heterocyclic group;
- R.sub.5 represents an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group or a group represented by --L--Z in which L represents a divalent linkage group;
- and Z represents an ionic group;
- and
- Q.sub.1, Q.sub.2 and Q.sub.3 each represents a single bond, an oxygen atom, a sulfur atom or a group represented by --N(R.sub.6)-- or --N(R.sub.6)--CO--, in which R.sub.6 represents a hydrogen atom or has the same meaning as R.sub.5 ;
- with the proviso that, when R.sub.5 represents a group represented by --L--Z, the R.sub.5 and the --L--Z which is directly bonded to Q.sub.3 are the same or different;
- two or more of R.sub.4, R.sub.5 and L may be combined with each other to from a ring;
- and
- the surface active compound may be represented by combining two or more of formulae (II) via R.sub.4, R.sub.5 and L.
