1. A method of manufacturing a toner comprising a modified polyester resin containing a structure represented by Formula (1a) or (1b), the method comprising the steps of
(a) dissolving a polyester resin in a solvent to form a polyester resin solution; (b) dispersing the polyester resin solution in an aqueous medium, followed by removing the solvent to form a polyester resin particle dispersion liquid; (c) adding a polymerizable monomer having a functional group selected from a group of a sulfonic acid group, a sulfonic salt group, and a sulfonic acid ester group, and a radical polymerization initiator the polyester resin particle dispersion liquid, followed by conducting radical polymerization to form a modified polyester resin particle dispersion liquid containing modified polyester resin particles; and (d) carrying out aggregation using at least the modified polyester resin particles to form particles of the toner,wherein, in Formula (1a) and (1b) R represents a hydrogen atom, a methyl group, or an ethyl group, R2 represents an aliphatic hydrocarbon which may be branched, or an aromatic hydrocarbon, and R3 represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or a phenyl group.
