摘要： A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support having positioned thereon a silver halide emulsion layer and a compound represented by the general formula (I): ##STR1## wherein R is a halogen atom or an alkyl group and n is 1, 2 or 3 and when n is 2 or 3 each R may be the same or different. Utilization of the compound represented by the general formula (I) aids in the elimination of the generation of fog without creating undesirable influences on the photographic properties of the material.

摘要： A silver halide photographic light-sensitive material and a developing process used in connection with that material are disclosed. The material is comprised of a support having thereon a silver halide emulsion layer containing a silver halide emulsion in which at least 80 mole % of the whole silver halide is composed of silver chloride, the mean grain size thereof is less than 0.4 .mu.m, and which contains more than 1.times.10.sup.-6 mole of a water-soluble rhodium salt per mole of silver at an optional period before finishing the first ripening in the production step for the silver halide emulsion. The material also contains 1.times.10.sup.-5 to 1.times.10.sup.-2 mole of polyalkylene oxide having a molecular weight of at least 600 or a derivative thereof per mole of silver. The process involves imagewise exposing the material and processing it in a developer containing 0.05 to 0.5 mole/liter of a dihydroxybenzene series developing agent, 0 to 0.05 g/liter of an auxiliary developing agent, at least 0.25 mole/liter of a free sulfite ion, at least 20 mg/liter of 5- or 6-nitroindazole, and an alkali of an amount sufficient for keeping the pH of the developer higher than 10.5. The material and processing are capable of providing good letter image quality in a short developing time.
