TONER AND TWO-COMPONENT DEVELOPER

The peak top molecular weight of the tetrahydrofuran-soluble component of the toner, as measured by gel permeation chromatography, is 4,000 or more and 6,500 or less. The tetrahydrofuran-insoluble component of the toner is 10% by weight or more and 30% by weight or less. When the endothermic peak te...

Summary:The peak top molecular weight of the tetrahydrofuran-soluble component of the toner, as measured by gel permeation chromatography, is 4,000 or more and 6,500 or less. The tetrahydrofuran-insoluble component of the toner is 10% by weight or more and 30% by weight or less. When the endothermic peak temperature T1 in the heating process and the exothermic peak temperature T2 during the cooling process originating from the ester wax is measured using a differential scanning calorimeter, the value T1-T2 is 15° C. or more and 30° C. or less.
