Summary: | To provide a toner that is excellent in all of low-temperature fixability and blocking resistance that are in trade-off, and durability.SOLUTION: A toner of the present invention is a toner containing a binder resin, a mold release agent, and a function imparting agent. The function imparting agent is a fatty acid amide having a melting point of 110°C or more and 160°C or less, and the toner is a toner not having an endothermic peak in an area ±20°C of the maximum peak of heat absorption of the fatty acid amide during temperature increase measured by a differential scanning calorimeter (DSC).SELECTED DRAWING: None
【課題】本発明は、トレードオフとなる低温定着性と耐ブロッキング性、また、耐久性のいずれも優れたトナーを提供することを目的とする。【解決手段】本発明のトナーは、結着樹脂と離型剤と機能付与剤とを含むトナーであって、前記機能付与剤が、融点110℃以上160℃以下の脂肪酸アミドであり、前記トナーが、示差走査熱量測定計(DSC)による昇温時に、前記脂肪酸アミドの吸熱の最高ピーク±20℃の領域に吸熱ピークを持たないトナーである。【選択図】なし |
