ABSTRACT:
An apparatus for producing silver halide grains of a uniform size wherein the apparatus comprises a mixing chamber comprising a casing of a polygonal-pillar shape within a reaction vessel filled with an aqueous colloid solution in such a manner that the interior of the mixing-chamber is filled with the aqueous colloid solution, where a water soluble silver salt solution and a water soluble halide solution are supplied by way of conduits to the lower end of the mixing chamber to dilute the solution with the aqueous colloidal solution contained in the mixing chamber, first agitation means disposed in the mixing chamber for rapidly agitating to mix and react both reaction liquids to form silver halide grains, and a second agitation means for immediately discharging the silver halide grains into the reaction vessel to ripen the silver halide grains outside of the mixing chamber.
