Zusammenfassung: | A toner comprises a toner particle that contains a binder resin having a crystalline resin and an amorphous resin, and a wax, wherein a matrix-domain structure made up of a matrix including the crystalline resin, and domains including the amorphous resin, is present in a cross-sectional observation of the toner, the crystalline resin has a specific monomer unit, in a differential curve, which is obtained through differentiation of a temperature-storage elastic modulus curve by temperature, with temperature being a horizontal axis and a common logarithm Log G′ of a storage elastic modulus G′ being a vertical axis as obtained in a viscoelasticity measurement of the toner, the differential curve has specific minimal values P1 and P2 within specific temperature ranges, and has storage elastic moduli G′ at the temperatures of the minimal values P1 and P2 lie in respective specific ranges. |
