PURPOSE:To effectively prevent fog and hindering of film hardening while maintaining sensitivity and gradation by developing a silver halide photographic sensitive material in the presence of a substd. triazole deriv. specified in structure. CONSTITUTION:The development processing is executed in the presence of the triazole deriv. represented by formula (I) in which R1 is H, alkyl, aralkyl, aryl, or heterocyclic, or alkenyl, R2 is alkyl, aryl, or alkenyl, and X is O or S, and said derivs. include the tautomer of the formula, thus permitting fog to be prevented or reduced without too much unfavorably affecting sensitivity and gradation. |
