Abstract:
A toner includes toner particles. The toner particles each include a toner mother particle containing a binder resin and a releasing agent. The binder resin includes a polyester resin and a vinyl resin. The vinyl resin includes a specific vinyl unit. A relationship 1.30≤Wabs/Wps≤2.00 is satisfied where Wabs represents an absolute molecular weight at a largest peak on an absolute molecular weight distribution curve of the binder resin as measured by size-exclusion chromatography using a multi-angle laser light scattering detector, and Wps represents a relative molecular weight at a largest peak on a relative molecular weight distribution curve of the binder resin in terms of polystyrene as measured by size-exclusion chromatography using a differential refractive index detector.
