发明名称 Process for producing toner
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.
