Abstract
There is disclosed a silver halide light-sensitive material and a method for forming image using thereof, in which a high contrast negative image useful in a photographic plate making process can be obtained in a processing solution with a pH lower than 11.0. The silver halide light-sensitive material comprises a support having provided thereon at least one silver halide emulsion layer and containing a hydrazine derivative in the above emulsion layer and/or a layer adjacent thereto. At least one compound represented by the following Formula (I) or (II) is contained in the above emulsion layer and/or a layer adjacent thereto: ##STR1## wherein A represents an organic group necessary for completing a hereto ring; B and C each represents a group constituted of one or more members selected from the group consisting of an alkylene group, an arylene group, an alkenylene group, --SO.sub.2 --, --SO--, --O--, --S--, and --N(R.sub.5)--, where R.sub.5 represents an alkyl group, an aryl group, or a hydrogen atom; R.sub.1 and R.sub.2 each represents an alkyl group; R.sub.3 and R.sub.4 each represents a substituent; and X represents an anion group, provided that X is not necessary when the compou…
