PROBLEM TO BE SOLVED: To obtain such a solid treating agent for a silver halide photographic sensitive material that does not cause deterioration in photographic characteristics or contamination even in continuous processes, and moreover, decrease in drying property and that causes little production of a powder by using an agent having specified bulk density of granules. SOLUTION: In the forming method of granules of a solid treating agent for a silver halide photographic sensitive material by granulating and drying, a granule having >=1.1 g/cm<3> bulk density is obtd. The granules obtd. by granulation has preferably 10μm to 1 mm average particle size, and more preferably 150 to 500μm. Moreover, it is preferable that in the distribution of the grain size, >=60% of the granules are included within the variance of 300±50μm. Moreover, each component such as an alkali agent, reducing agent, preservative, etc., is preferably individually granulated in the granulating process. The bulk density of the treating agent is preferably >=1.0 g/cm<3> from the viewpoint of the solubility and the effect. The bulk density of the solid treating agent is especially preferably 1.1 to 1.3 g/cm<3> .
