More Information
Summary:A toner comprising a toner particle comprising a binder resin, wherein the binder resin comprises an amorphous polyester A and a crystalline polyester C; the amorphous polyester A has an amorphous polyester segment a1 and a2; the amorphous polyester segment a2 has a monomer unit of a specific alcohol a0; the crystalline polyester C is a polymer having a crystalline polyester segment c2 and a crystalline segment c1 bonded to the end of the crystalline polyester segment c2; the crystalline polyester segment c2 has a monomer unit of a specific alcohol b0; an absolute value of a difference between a carbon number of the linear aliphatic polyhydric alcohol a0 and a carbon number of the linear aliphatic polyhydric alcohol b0 is 4 or less; and SP values of the polyester segment a1 and a2, and the crystalline segment c1 and the crystalline polyester segment c2 satisfy specific relationships.
