Polyester resin for toners, method for producing same, and toner

Abstract

The invention relates to a polyester resin for toner, the polyester resin containing a monomer unit derived from isosorbide and a monomer unit derived from 1,2-propanediol, in which the proportion of the monomer unit derived from isosorbide is from 2 to 11% by mass with respect to the total mass of the polyester resin, and a glass transition temperature (Tg) of the polyester resin for toner is from 56 to 70° C. According to the invention, it is possible to provide a polyester resin for toner from which toner excellent in storage stability, fixing property, hot offset resistance and image stability in the case of using isosorbide is obtained, and a method for producing the polyester resin for toner. In addition, the toner obtained from the polyester resin for toner of the invention is excellent in storage stability, fixing property, hot offset resistance and image stability in the case of using isosorbide.
