Abstract
A composition for developing a silver halide photographic light-sensitive material is disclosed. The composition has a form of a tablet or granule and comprises an organic development inhibitor having a solubility of not higher than 1 % by weight in an aqueous medium having a pH value of 6 to 12, and a water-soluble or alkali-soluble polymer having a melting point of 30.degree. C. to 100.degree. C. in an amount of not less than 5% by weight of total weight of the composition. The granules or tableted composition of the invention is preferably produced in a process comprising steps of (1) melting the polymer, (2) dissolving the organic development inhibitor in the melted polymer, (3) mixing the melted polymer containing the component with the remaining components of the composition, and (4) granulating or tableting the mixed composition. The composition is friendly for environment and is excellent in stability, conservability.
