Zusammenfassung:Provided is a yellow toner that has excellent pigment dispersibility, and thus gives a high image density and causes little fog. A yellow toner of the present invention includes at least a binder resin and a yellow pigment, wherein the binder resin is a copolymer that contains 67 to 88% by mass of a styrene-based monomer unit and 12 to 33% by mass of a alkyl (meth)acrylate monomer unit, wherein a content of the yellow pigment is 3 to 15 parts by mass with respect to 100 parts by mass of the binder resin; and wherein a interfacial tension of a mixed solution of 9 parts by mass of the yellow pigment, 72 parts by mass of styrene and 28 parts by mass of n-butyl acrylate with respect to water, is 5 to 19 mN/m.
