发明名称 TONER
摘要 An object of the present invention is to provide a toner which: is excellent in fixing ability such as low-temperature fixability, hot offset property, and separability even in a fixing system excellent in quick start property and energy saving property; has high gloss; and is excellent in development stability and transferability irrespective of environments. The toner of the present invention includes toner particles each containing at least a binder resin and a colorant, in which, in a case where a tetrahydrofuran (THF) insoluble matter of the binder resin in the toner when the toner is subjected to Soxhlet extraction with THF for 2 hours is represented by A (mass %), a THF insoluble matter of the binder resin in the toner when the toner is subjected to Soxhlet extraction with THF for 4 hours is represented by B (mass %), a THF insoluble matter of the binder resin in the toner when the toner is subjected to Soxhlet extraction with THF for 8 hours is represented by C (mass %), and a THF insoluble matter of the binder resin in the toner when the toner is subjected to Soxhlet extraction with THF for 16 hours is represented by D (mass %), A, B, C, and D satisfy the following expression: (A-B)/2>(B-C)/4>(C-D)/8 where 40<A<=75 (mass %) and 1.0<D<40 (mass %).
