    摘要: The toner comprises a toner particle that comprises a binder resin-containing core particle and a thermosetting resin-containing shell on the surface of the core particle, wherein the binder resin includes at least one of (i) a vinyl resin and a polyester resin and (ii) a hybrid resin in which a vinyl resin and a polyester resin are bonded; the polyester resin comprises in a main chain thereof a cyclic structure, and the content of the polyester resin in the tetrahydrofuran-soluble matter of the toner is at least 51 mass%; the vinyl resin comprises a prescribed monomer unit; the thermosetting resin is at least one resin selected from melamine resins, urea resins, and oxazoline group-bearing vinyl resins; and the average circularity of the toner is in a prescribed range.

    摘要: A toner, including: a copolymerization resin, wherein the copolymerization resin includes: a unit derived from a polyester resin including a polycarboxylic acid having a valence of 2 or more and a polyol having a valence of 2 or more; and a unit derived from a resin having a polyhydroxycarboxylic acid skeleton, where the unit derived from the resin having a polyhydroxycarboxylic acid skeleton is bonded to the unit derived from the polyester resin via at least one of a urethane group and a urea group, and wherein the toner has a relative degree of crystallization of 10% or more and less than 50%.
