RESIN COMPOSITION FOR TONER AND TONER

摘要

A resin composition for toners which comprises a vinyl copolymer obtained mainly from a styrene monomer and a (meth)acrylic ester monomer, a Fischer/Tropsch wax, and a polystyrene block copolymer, characterized in that the vinyl copolymer has a molecular weight distribution as determined by gel permeation chromatography in which at least two peaks are present respectively in the molecular-weight region of from 5,000 to 20,000 and the region of molecular weights not lower than 500,000, that the wax is contained in an amount of 2 to 10 wt.%, and that the block copolymer is contained in an amount of 0.5 to 5 wt.%; and a toner containing the resin composition.
