ABSTRACT:
The present invention relates to a production method of a toner for developing an electrostatic charge image having an excellent charging property, the method comprising the steps of: forming aggregative particles in a dispersion including at least dispersed resin particles to prepare an aggregative particle dispersion; adding a resin-containing fine particle dispersion containing dispersed resin-containing fine particles into the aggregative particle dispersion and mixing therewith to form adhered particles having said resin-containing fine particles adhering to said aggregative particles; and heating said adhered particles to be fused, wherein concentration of a dissociation group of said resin-containing particles per unit volume is lower than that of a dissociation group of said resin-containing fine particles per unit volume.
