TONER, TONER STORAGE UNIT, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD

To provide a toner that can achieve both low temperature fixability and heat-resistant storage property at a high level, can prevent the occurrence of an abnormal image due to filming while maintaining a good cleaning property, and is excellent in prevention of transfer unevenness, image density, and fine line reproducibility during continuous printing.SOLUTION: A toner has resin fine particles and an external additive on a surface of a toner base particle containing at least a binder resin and a mold release agent. The standard deviation of the distances between the adjacent resin fine particles present in the surface of the tone base particle is less than 600 nm. The external additive contains aspherical coalesced particles obtained by coalescing primary particles, and the primary particles make up 30% or less in 1,000 particles of the external additive.SELECTED DRAWING: None 【課題】低温定着性と耐熱保存性を高レベルに両立でき、良好なクリーニング性を維持しつつ、フィルミングによる異常画像の発生を抑制でき、連続印刷時において転写ムラの抑制、画像濃度、及び細線再現性に優れたトナーの提供。【解決手段】少なくとも結着樹脂及び離型剤を含有するトナー母体粒子の表面に、樹脂微粒子及び外添剤を有するトナーであって、前記トナー母体粒子の表面に存在する隣り合う前記樹脂微粒子間の距離の標準偏差が６００ｎｍ未満であり、前記外添剤が、一次粒子同士が合着されてなる非球形の合着粒子を含有し、前記外添剤の粒子１，０００個中に占める一次粒子の割合が３０％以下であるトナー。【選択図】なし
