Title:
トナー製造方法及び重合体
Document Type and Number:
Japanese Patent JP6921678
Kind Code:
B2
Abstract:
A toner production method including: a melt-kneading step of melt-kneading a resin composition including a binder resin, a colorant, a wax, and a wax dispersant to obtain a melt-kneaded product; and a pulverizing step of pulverizing the melt-kneaded product. Where the temperature of the melt-kneaded product at the end of the melt-kneading step is Tk (° C.), and the softening point of the wax dispersant is Tm (° C.), the relationship of −18≤[Tk−Tm]≤10 is satisfied. The wax dispersant is a polymer in which a styrene acrylic polymer is graft-polymerized to a polyolefin. The styrene acrylic polymer has a monomer unit derived from α-methylstyrene and a monomer unit derived from a cycloalkyl (meth)acrylate.
