(57) [Abstract] (with correction) [Problem] An ester wax is uniformly dispersed in a binder resin, has a good fixing property, an offset resistance, a blocking resistance, a multi-sheet durability and a negative sleeve. Provide a toner excellent in ghost suppression and the like. The binder resin contains a reaction product of a vinyl copolymer and a polyester resin, and the binder resin contains 2 to 60 parts by weight of a component insoluble in ethyl acetate and a component soluble in ethyl acetate. The content of the polyester resin component (Gp) in the component insoluble in ethyl acetate is 40 to 98% by weight, and the content of the polyester resin component (Sp) in the component soluble in ethyl acetate is 40 to 98% by weight. Content 2 0 to 90% by weight, and (Sp / Gp) is 0.5 to 1. |
