The pulverization chamber is enlarged at its part on the side more upstream than the outermost edge of the second impact face so that the cross-sectional area of the inside of the chamber at that part is larger than that of the inside of the chamber corresponding to the outermost edge of the second impact face. The tip of the first impact face is positioned on the side more upstream than the downstream side edge of the first sidewall. The pulverization can be conducted in a very high efficiency with the pulverizer. Also, a process for producing a toner for developing electrostatic images using the pulverizer is disclosed.

摘要： A process for producing a toner. The process has the steps of dispersing a fine-particle colorant in a liquid monomer mixture containing at least a liquid polymerizable monomer, dispersing the resulting colorant-dispersed liquid monomer mixture in an aqueous dispersion medium to form particles of a polymerizable monomer composition, and polymerizing polymerizable monomers present in the particles in the aqueous dispersion medium to form toner particles. In the dispersion step, a media particle agitation type wet-dispersion machine is used as a dispersion means. The dispersion machine has a cylindrical vessel having a first wall surface having a liquid-feed opening and a second wall surface having a liquid-discharge opening. The vessel is inside provided with an inner chamber and an outer chamber which are partitioned with a cylindrical separator having slits, a rotor set in the inner chamber rotatably by the rotary drive motion of a drive shaft, and a plurality of spherical media particles held in the inner chamber.
