BINDER RESIN FOR TONER, METHOD FOR PRODUCING SAME, AND TONER FOR ELECTROPHOTOGRAPHY USING SUCH RESIN

摘要

Disclosed is a binder resin for toner which contains a styrene acrylic resin having a gel component and a small amount of volatile component. Also disclosed are a method for producing such a binder resin and a toner employing such a binder resin. A binder resin (A) for 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 (AIS) of the gel component is 1 mass% <= AIS <= 50 mass% and the content (AVO) of the volatile component in the resin is AVO <= 200 ppm.
