PROBLEM TO BE SOLVED: To provide a toner which includes a high molecular weight resin that can reduce degradation and be dispersed by a solvent-free process, and is produced from a hybrid resin that can significantly reduce cost.SOLUTION: The toner comprises a branched polyester suitable for use in solvent-free emulsification. The branched polyester has a first original weight average molecular weight before undergoing the solvent-free emulsification, and a second weight average molecular weight after undergoing the solvent-free emulsification. The branched polyester has a structure that limits degradation of the polyester during the solvent-free emulsification to less than about 20 percent of the first original weight average molecular weight. The branched polyester comprises a polyester as a compound of a specific structure, an optional wax, and an optional colorant. |
