摘要:
The invention provides a toner comprising a binder resin, a colorant, and a charge control agent comprising a charge control substance supported by an inorganic porous material, and having been subjected to thermal fairing treatment. Also disclosed are a toner obtained by a process comprising the steps of: kneading a composition containing a binder resin, a colorant and a charge control agent comprising an ionic or neutral substance supported by an inorganic porous material; pulverizing the kneaded product; adding the pulverized product to a solvent immiscible with water; dispersing the mixture in an aqueous medium; and removing the solvent by at least one of heating and pressure reduction, and a toner comprising associated particles formed from: primary particles obtained from an emulsion of a binder resin; a colorant; and a charge control agent comprising a water soluble charge control substance incorporated in inorganic fine particles.
