Color toner and process for fixing the same

Abstract

A color toner for developing electrostatic images including a resin component and a colorant, said resin component comprising a THF (tetrahydrofuran)-­soluble and containing substantially no toluene-­insoluble; wherein the THF-soluble provides a molecular weight distribution in the GPC (gel permeation chromatography) thereof such that there are a peak (Mp1) in the molecular weight range of 500 to 2,000, and a peak (Mp2) in the molecular weight range of 10,000 to 100,000; the weight-average molecular weight (Mw) is 10,000 to 80,000, the number-average molecular weight (Mn) is 1,500 to 8,000, and the rate of Mw/Mn ≧ 3.
