    摘要： A silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer and at least one coupler represented by the following general formula (I): ##STR1## wherein (Q) represents a pyrazoloazole type color image forming coupler residue; L.sub.1 and L.sub.2 each represents a methylene group or an ethylene group; l and m each represents 0 or 1; R.sub.1 represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group; R.sub.2 represents a group connecting with A through a carbon atom, an oxygen atom, a nitrogen atom or a sulfur atom; A represents a carbon atom or a sulfur atom; n represents 1, when A is a carbon atom, or 1 or 2, when A is a sulfur atom; B represents a carbon atom, an oxygen atom, a nitrogen atom or a sulfur atom; X represents an atomic group necessary to form a ring; R.sub.1 and R.sub.2 may connect with each other to form a ring; and B and R.sub.2 may connect with each other to form a ring, when B is a carbon atom or a nitrogen atom.A method of forming a color image comprising developing a silver halide photographic material with a developing solution containing an aromatic primary amine in the presence of a at least one coupler represented by the general formula (I) described above is also disclosed.The coupler represented by the general formula (I) has good color reproducibility due to being free from the undesirable subsidiary absorption of the dye formed therefrom and a high color forming rate, and provides a sufficiently high color density even when an amount of silver employed in the light-sensitive material is reduced or the light-sensitive material is subjected to a rapid processing method and a low level of fog. Further, the dye formed from the coupler exhibits excellent fastness.
