摘要:
The invention is to provide a toner excellent in fixing property, high-temperature offset resistance and blocking resistance, and having an excellent developing property. The invention provides a toner including at least a binder resin and a colorant, wherein: the binder resin contains a hybrid resin which contains a polyester-type resin unit by 50 mass % or more and in which a polyester-type resin component and a vinyl-type resin component are chemically bonded; the toner contains 3 to 50 mass % of a tetrahydrofuran-insoluble matter derived from the binder resin; the tetrahydrofuran-insoluble matter contains a hybrid resin; and a tetrahydrofuran-soluble matter, obtained by hydrolyzing the tetrahydrofuran-insoluble matter and separating by filtration, has, in a GPC-measured molecular weight distribution, a main peak within a molecular weight range of 50,000 to 500,000.
