Two or more solutions comprising an organic pigment solution in which an organic pigment is dissolved in a good solvent, and a poor solvent compatible with the good solvent, or a solution of the poor solvent are allowed to flow through a microchannel in a non-laminar state; and organic pigment fine particles are deposited from the organic pigment solution in a course of flowing through the microchannel by changing the solubility of the organic pigment solution with the poor solvent or the solution of the poor solvent. As a result, nanometer-scale monodisperse organic pigment fine particles can be produced in a stable manner. |
