Abstract

PURPOSE:To suppress the generation of fogging in a dot pictures, and to improve the contrast of the image by developing a silver halide photographic sensitive material contg. at least one layer of a silver halide emulsion layer and a specified compd. in the presence of a specified compd. CONSTITUTION:The silver halide photographic sensitive material contg. at least one layer of the silver halide emulsion layer and the compd. shown by formula I, is developed in the presence of the compd. shown by formula II. In formula I, R1 and R2 are each aryl group, etc., R is a org. bonding group, (n) is 0-6, (m) is 0 or 1, and when (n) is >=2, groups R may be the same or the different with each other. In formula II, L1-L4 are a divalent hydrocarbon group, J1 and J2 are each -O- group, etc., Y is hydrogen atom, a bivalent bond or amidino group, Z is a heterocyclic group, G is a sulfonic acid or carboxyl group, etc., R<1> and R<2> are each hydrogen atom, etc., (k), (l), (m) and (n) are each an integer of 0-2, (p) is an integer of 0-4, (q) is an integer of 1-4, (r) is an integer of 1-2, and when G is carboxyl group, (m) is an integer of 1-2, when Y is a divalent bond, (r) is 2.
