Abstract
To provide a nonmagnetic toner excellent in low-temperature fixability, heat-resistant storage property, durability, and charge rise performance.SOLUTION: A nonmagnetic toner includes a nonmagnetic toner particle containing a crystalline resin A, an amorphous resin B, and a colorant. The crystalline resin A has a monomer unit (a), and the amorphous resin B has a monomer unit (b). A content of the crystalline resin A in the nonmagnetic toner is 10.0 to 58.0 mass %, the sum of the contents of the crystalline resin A and the amorphous resin B in the nonmagnetic toner is 65.0 mass % or more, and a content of the monomer unit (a) in the crystalline resin A is 50.0 to 100.0 mass %. Using SPA[(J / cm3)0.5] for a SP value of the crystalline resin A and using SPB[(J / cm3)0.5] for a SP value of the amorphous resin B, the SPA and the SPB satisfy 0.15≤SPB-SPA≤2.00.SELECTED DRAWING: None
