Abstract:
Provided is a method for manufacturing a toner having both low-temperature fixability and storability as well as good charging performance by thoroughly phase separating a crystalline resin and an amorphous resin in the toner while uniformly dispersing the crystalline resin in the form of minute domains, in which a method for manufacturing a toner containing a crystalline resin and an amorphous resin compatible with the crystalline resin includes a compatibilization step of compatibilizing the crystalline resin and the amorphous resin to obtain a compatibilized blend, and a solvent treatment step of treating the compatibilized blend with an organic solvent, wherein the organic solvent is a good solvent for the amorphous resin and a poor solvent for the crystalline resin.
