Binder resin for the toner, method for producing the same, and toner for electrophotography using the resin

摘要

Disclosed is a binder resin for a toner which contains a styrene-acrylic resin having a gel component and a small amount of a volatile component. Also disclosed are a method for producing the binder resin and a toner employing the binder resin. A binder resin (A) for a toner contains a styrene-acrylic resin having a structure derived from a carboxyl group and a structure derived from a glycidyl group, wherein the content (A_IS) of a gel component is 1 mass %<=A_IS<=50 mass % and the content (A_VO) of a volatile component in the resin is A_VO<=200 ppm.
