Abstract
(EN)
The present invention provides a method for manufacturing toner for electrostatic charge image development, the method comprising: a dispersion step for obtaining a colored resin particle dispersion liquid by performing dispersion treatment, by which a cavitation effect is obtained, on colored resin particles containing a binding resin, a colorant, a charging control agent, and a mold release agent in an aqueous dispersion medium; a heating step for performing heating treatment on the colored resin particle dispersion liquid at a temperature higher than or equal to the glass-transition temperature of the colored resin particles and lower than or equal to 95°C for a heating time of 5 minutes to 10 hours inclusive.
