Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a toner binder that has excellent low-temperature fixability, heat-resistance storage stability, and hot offset resistance, and has excellent blocking resistance of paper after continuous printing; and a toner containing the toner binder.SOLUTION: A toner for electrostatic charge image development includes at least a binder resin and colorant, where the binder resin contains a crystalline resin (A) and the crystalline resin (A) contains two or more types of crystalline resin (a), and a combination of endothermic peak temperatures consisting of the entire respective endothermic peak temperatures of the two or more types of crystalline resin (a) has two or more different endothermic peak temperatures.
【課題】低温定着性、耐熱保存性及び耐ホットオフセット性に優れ、かつ、連続で印刷した際の紙の耐ブロッキング性に優れるトナーバインダー、並びにそのトナーバインダーを含有するトナーを提供する。【解決手段】少なくとも結着樹脂、着色剤を含む静電荷像現像用トナーにおいて、結着樹脂が結晶性樹脂(A)を含有し、結晶性樹脂(A)が、2種以上の結晶性樹脂(a)を含有してなり、2種以上の結晶性樹脂(a)のそれぞれの吸熱ピーク温度の全体からなる吸熱ピーク温度の組が、2つ以上の異なる吸熱ピーク温度を有することを特徴とする静電荷像現像用トナー。【選択図】なし |
