Polyester resin emulsion, resin particle, toner, and method of manufacturing toner

Abstract

A polyester resin emulsion contains resin particles (S) containing an amorphous polyester resin (A) in which the carboxyl group of a polyester resin obtained by polycondensation of the alcohol component and the carboxylic acid component is neutralized by a basic substance and an aqueous medium where the resin particles (S) are dispersed, wherein the following relationship 1 is satisfied: 0.89 ≤ B / A ≤ 2.23 , where A represents an acid value of the amorphous polyester resin (A) and B represents an amount in mmol/g of cation derived from the basic substance.
