摘要:
A silver halide photographic material which contains a light-sensitive silver halide emulsion and an internally fogged silver halide emulsion is development-processed in the presence of at least one compound selected from the group consisting of compounds represented by the general formulae (I) and (II) and at least one azaindene having a mercapto group to exhibit high photographic speed, high contrast and high maximum image density:R.sub.1 --(R.sub.3).sub.l X}.sub.n R.sub.3 '--R.sub.2 (I)wherein R.sub.1 and R.sub.2 each represents a hydrogen atom, an aryl group, an aryl group, or a heterocyclic group; R.sub.3 and R.sub.3 ' each represents an alkylene group, an arylene group, a heterocyclic group; X presents ##STR1## R.sub.4 represents a hydrogen atom or --R.sub.5 --Y}.sub.m R.sub.5 '--R.sub.6 ; R.sub.5 and R.sub.5 ' have the same meanings as R.sub.3 and R.sub.3 '; R.sub.6 has the same meaning as R.sub.1 and R.sub.2 ; Y represents ##STR2## R.sub.7 has the same meaning as R.sub.1 and R.sub.2 ; l represents 0 or 1, n represents an integer of 1 to 110, and m represents an integer of 0 to 10, and at least one X therein must be a sulfur atom: ##STR3## wherein Q represents atoms necessary to form a heterocyclic ring, and A represents an alkyl group, or an aryl group.
