Abstract

　現像性が良好で且つカブリが無く、ハーフトーン部位においても黒色度が高く、濃度ムラのない画像を安定的に形成可能な磁性トナーを提供する。結着樹脂及び磁性酸化鉄粒子を少なくとも含有する磁性トナー粒子を有する磁性トナーであって、磁性酸化鉄粒子は、磁性酸化鉄粒子を酸水溶液に溶解し溶解液を得、磁性酸化鉄粒子が全て溶解された溶解液中に含まれるＦｅ元素量を総Ｆｅ元素量としたときに、総Ｆｅ元素量の１０質量％が溶解液に存在する状態まで磁性酸化鉄粒子が溶解された溶解液（Ｆｅ元素溶解率１０質量％溶解液）中に含まれるＦｅ元素量に対するＦｅ元素溶解率１０質量％溶解液中に含まれるＦｅ（２＋）量の割合Ｘが３４質量％以上５０質量％以下であり、該磁性トナーは、温度４０°Cで測定される誘電正接が、（ａ）周波数１０，０００Ｈｚにおける誘電正接Ａが１．０×１０－６以上１．０×１０－１以下、（ｂ）周波数１，０００Ｈｚにおける誘電正接Ｂが１．０×１０－６以上１．０×１０－１以下、（ｃ）誘電正接Ａの誘電正接Ｂに対する比（Ａ／Ｂ）が０．１０以上１０．００以下、を満足することを特徴とする磁性トナー。
