ABSTRACT A silver halide photographic light-sensitive material comprising at least one compound represented by the general formula [I] and a-t least one compound represented by the general formula [XII]: [I] Image (wherein Z represents a group of non-metallic atoms necessary to complete a nitrogen-containing heterocyclic ring which may have a substituent; X represents a hydrogen atom or a substituent capable of being split off upon reaction with an oxidation product of a color developing agent; and R represents a hydrogen atom or a substituent): [XII] Image (wherein R21, R22 and R24 are independently selected from the group consisting of a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group and a heterocyclic group provided that the above-listed group may have a substituent; R2 3 is selected from the group consisting of an alkyl group, a cycloalkyl group, an alkenyl group, and an aryl group of which respective groups have a substituent; R2 4 is a group cabable of being a substituent to the benzene ring of the formula; 1 is an integer of 0 to 4;J is selected from the group consisting of Image and . Image wherein, R25 and R2 6 are independently selected from a hydrogen atom and an alkyl group which may have a substituent; and m is 0 or 1 provided that R2, and R22 may be combined with each other to form a 5- or 6-membered ring, that when 1 is 2 or more R24s' may he either the same or different and that R24 may cooperatively be combined with R21 or R2 2 to form a 5- or 6- membered nitrogen-containing ring together with the nitrogen atom adjacent to R2, or R2 2 and a part of the phenylene group to which R2 4 is attached.
