发明名称 TONER
摘要 Provided is a toner including at least: a binder resin; and a colorant, in which: the binder resin contains at least a polyester unit and a vinyl copolymer unit; a main peak MpA is present in the molecular weight region of 2,000 to 7,000 in a molecular weight distribution measured by means of gel permeation chromatography (GPC) of a specific tetrahydrofuran (THF) soluble matter A measured by a specific method; a main peak MpB is present in the molecular weight region of 5,000 to 10,000 in a molecular weight distribution measured by means of GPC of a specific THF soluble matter B which contains a component of a molecular weight region of 100,000 or less in range from 70 to 100 mass %, and the peak molecular weight MpA of the THF soluble matter A and the peak molecular weight MpB of the THF soluble matter B satisfy a specific equation.
