POLYESTER RESIN, METHOD FOR PRODUCING SAME, AND TONER

摘要

The present invention relates to a polyester resin which comprises a constituent unit represented by general formula (1), a constituent unit derived from a compound having a bisphenol skeleton and a constituent unit derived from a polyvalent carboxylic acid, and wherein the constituent unit derived from a compound having a bisphenol skeleton is contained in an amount of 20 parts by mole or more per 100 parts by mole of the constituent unit derived from a polyvalent carboxylic acid. The present invention is able to provide a polyester resin which has excellent solubility in a solvent and excellent pulverization properties, and which provides a toner having excellent storage stability.;
