PROBLEM TO BE SOLVED: To provide a toner in which wax is uniformly dispersed in a binder resin, has a good fixing property, and is excellent in offset resistance, blocking resistance, and durability for multiple sheets. provide. SOLUTION: The binder resin includes a vinyl resin, a polyester resin, and a hybrid resin component having a vinyl polymer unit and a polyester unit; 50-85% HF soluble component, 15-5% insoluble component 0%; 40-98% of ethyl acetate-soluble component, 2-60% of insoluble component (W4); 55-90% of chloroform-soluble component, 10-45% of insoluble component (W6) contained; a value of W4 / W6 is 1.1 to 4.0; a component having a main peak in a molecular weight range of 4000 to 9000 and a molecular weight of 500 to less than 10,000 is 3 5.0 to 65.0% (A1), components having a molecular weight of 10,000 to less than 100,000 are 25.0 to 45.0% (A2), and A1 / The value of A2 is 1.05 to 2.00. |
