Abstract
A toner including toner particles containing at least a binder resin and a colorant. The binder resin is a vinyl-based resin. The toner contains a THF insoluble matter in a quantity of 0.0 mass % or more to less than 16.0 mass %. The toner has a main peak in a molecular weight domain Drranging from 5,000 to 80,000 in measurement of THF soluble matter of the toner with a gel permeation chromatogram (GPC)-differential refractive index detector (RI), and the toner has a main peak in a molecular weight domain Dmranging from 10,000 to 120,000 and at least one peak in a molecular weight domain Dmranging from 300,000 to 7,000,000 in the GPC-RI measurement in measurement with a GPC-multi-angle laser light scattering detector (MALLS).
