Abstract
A nonmagnetic toner comprises a nonmagnetic toner particle. The nonmagnetic toner particle comprises a crystalline resin A, an amorphous resin B, and a colorant. The crystalline resin A has a monomer unit (a). 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. A content of the monomer unit (a) in the crystalline resin A is 50.0 to 100.0 mass %. Using SPA [(J/cm)] for a SP value of the crystalline resin A and using SPB [(J/cm)] for a SP value of the amorphous resin B, SPA and SPB satisfy 0.15≤SPB−SPA≤2.00.
