Toner resin composition and toner

摘要

A toner resin composition composed of a vinyl-type copolymer which has styrene-type monomers and (meth)acrylic ester-type monomers as the main ingredients, a low-melting-point crystalline compound, and a block compolymer of polystyrene and polyolefin wherein the average particle area is 0.5-20 mum2 and the maximum particle area is 30 mum2 or less in any 25 mumx25 mum area when transmission electron microscopy is used to observe said low-melting-point crystalline compound which forms domains in the domain-matrix structure formed by said vinyl-type copolymer and the low-melting-point crystalline compound.To provide a toner resin composition and toner which have superior fixability, anti-offset properties, and shelf stability.
