ABSTRACT:
There is disclosed a silver halide photographic light-sensitive material which contains, on a support, a specific nitrogen-containing heterocyclic compound, and a divalent metal cation that is an acid with intermediate hardness/softness classified in accordance with the HSAB principle, in an amount 1 to 300 times the number of moles of the nitrogen-containing heterocyclic compound. The light-sensitive material can form an image with high sensitivity and low fogging, both in heat-development processing characterized by its ease and rapidness, and in usual liquid-developing processing that is widely used.
