Abstract
A method of manufacturing a tablet processing agent for a silver halide photographic light-sensitive material is disclosed, which comprises the step of molding particles into tablets at a compression pressure of 400 to 4500 kg/cm.sup.2 and at a compression dwell time of 0.015 to 1.000 second to obtain the tablet processing agent, wherein the particles comprises a compound selected from the group consisting of a p-phenylene diamine and its derivatives, a hydroxylamine and its derivatives, an alkali metal carbonate, an amino polycarboxylic acid ferric complex and a thiosulfate.
