摘要:
The present invention relates a toner for developing electrostatic images, comprising: a resin composition, which contains a binder resin and low molecular weight wax, and a coloring agent, wherein the binder resin does not substantially contain insoluble tetrahydrofuran (THF) component, its chromatograph measured with soluble tetrahydrofuran (THF) component has a main peak in a region of a molecular weight of 2,000 to 30,000 and a subpeak or a shoulder in a high molecular weight region of a molecular weight of 100,000 or more, a ratio of weight average molecular weight (Mw)/number average molecular weight (Mn) thereof is 30 or more, the high molecular weight region has a crosslinking monomer unit as a component monomer unit and the binder resin contains high molecular weight polymer having a Mw of 1,200,000 or more polymerized by using both polyfunctional initiator and a mono-functional initiator. Moreover, the present invention relates to a method of manufacturing a resin composition for producing a toner.
