Summary:To ensure good print performance in all environmental extremes.SOLUTION: An emulsion aggregation toner contains toner particles and a reactive charge control agent. The toner particles comprise one kind of resin, a colorant, and a wax. The reactive charge control agent comprises: one kind of positive charging compound selected from among an amine compound having at least 3 carbon atoms, an ammonium compound having at least 3 carbon atoms, a phosphonium compound having at least 3 carbon atoms, and a boronium compound having at least 3 carbon atoms; and one kind of reactive anchoring compound selected from among amino, epoxy, carboxylic acid, hydroxyl, silanol, cyanide, anhydride, aldehyde, ketone and vinyl. The charge control agent optionally further comprises a negative charging compound selected from among aromatic carboxylic acid, silanol, phenol, pyranone and furanone.SELECTED DRAWING: None 【課題】全ての環境的極限下での良好な印刷性能を保証する。【解決手段】エマルション凝集トナーであって、1種の樹脂と着色剤とワックスとを含むトナー粒子並びに反応性電荷制御剤で、3以上の炭素原子を有するアミン化合物、3以上の炭素原子を有するアンモニウム化合物、3以上の炭素原子を有するホスホニウム化合物、3以上の炭素原子を有するボロニウム化合物から選択される1種の正帯電化合物と、アミノ、エポキシ、カルボン酸、ヒドロキシル、シラノール、シアン化物、無水物、アルデヒド、ケトン、ビニルから選択される1種の反応性アンカー化合物とを含み、電荷制御剤は芳香族カルボン酸、シラノール、フェノール、ピラノン、フラノンから選択される負帯電化合物を更に含む反応性電荷制御剤を含む。【選択図】なし
