Summary:PROBLEM TO BE SOLVED: To provide a toner that can be fixed at low temperature and reduce adhesion of ejected sheets in a LBP accelerated compared with the prior art.SOLUTION: A toner includes toner particles containing at least a charge control agent and a crystalline resin. In endothermic amount measurement of the toner, when the toner is held at 80°C for five minutes, cooled to 60°C at 750°C/min, and held at 60°C, the time t1/2 required until 50% of the area of an endothermic peak is generated is 0.03 minutes or more and 0.32 minutes or less; the charge control agent is a compound of the formula (1).SELECTED DRAWING: None 【課題】従来よりも高速化されたＬＢＰにおいて、低温定着化した上で排紙接着を抑制することが可能なトナーを提供すること。【解決手段】荷電制御剤、結晶性樹脂を少なくとも含有するトナー粒子を有するトナーであって、トナーの吸熱量測定において、８０℃で５分保持後、７５０℃／ｍｉｎで６０℃まで冷却し、６０℃で保持した際の発熱ピークの面積の５０％が生じるまでの時間ｔ１／２が０．０３分以上０．３２分以下であり、荷電制御剤が式〔１〕の化合物である。【選択図】なし
