PROBLEM TO BE SOLVED: To provide a media stirrer mill in which a composing material of a toner for electrophotography and an inkjet ink or the like is finely grained, dispersion media are not unevenly distributed in a dispersion chamber but are made to uniformly exist in each dispersion space region for dispersion, the dispersion media can be imparted with sufficient kinetic energy, dispersion efficiency is improved, and a uniform particle diameter dispersion object can be obtained.SOLUTION: A media stirrer mill includes: a dispersion container; and a stirring member rotatable in the dispersion container, wherein a material to be dispersed is dispersed in a dispersion chamber formed in a gap between the stirring member and the dispersion container. The dispersion container includes concavities having arc-like bottoms and convexities on its inner wall surface. |
