ABSTRACT:
A toner is disclosed including toner particles containing a binder resin and a colorant. The binder resin contains a vinyl resin. In the high-temperature GPC-RALLS-viscometer analysis of the o-dichlorobenzene-soluble matter of the toner, a weight-average molecular weigh of absolute molecular weights measured with a viscosity detector is in a specific range. In the o-dichlorobenzene-soluble matter, a component with the absolute molecular weight of 10,000 or less and a component with the absolute molecular weight of 1,000,000 or more are present in specific proportions, respectively. The intrinsic viscosity of the toner is in a specific range.
