To provide a method for manufacturing a ground toner with improved grinding efficiency and/or classification efficiency, an air flow grinder for manufacturing a ground toner, and an air flow classifier for manufacturing a ground toner.
The method for manufacturing a ground toner includes: a process of melt-kneading a material mixture including a binder resin and a colorant, a process of coarsely grinding the kneaded product after solidification by cooling; a process of finely grinding the coarsely ground product with an air flow grinder equipped with an ionization means; and a process of classifying the finely ground product, wherein, in the fine grinding process with the air flow grinder, air used for air flow grinding is ionized by the ionization means and the electrostatically aggregated ground product is discharged by the ionized air.
