Process of forming silver halide grains.

摘要

A process of forming silver halide grains which comprises disposing a mixer outside of a reaction vessel for causing the nucleus formation and crystal growth of silver halide grains. The process further includes the steps of: supplying an aqueous solution of a water-soluble silver salt, an aqueous solution of a water-soluble halide, and an aqueous protective colloid solution into the mixer to form fine, silver halide grains therein; immediately supplying the fine grains into the reaction vessel; and performing the nucleus formation and crystal growth of the silver halide grains in the reaction vessel. The formation of the fine grains is controlled by controlling the flow rates of the solutions being supplied to the mixer and the r.p.m. of a stirrer provided in the mixer.
