description | To provide a yellow toner that maintains excellent low temperature fixability and realizes high electrification characteristic even under high temperature and high humidity environment.SOLUTION: A yellow toner has toner particles containing a binder resin, a crystalline resin, and C.I. Pigment Yellow 180. The C.I. Pigment Yellow 180 has a content of 3 mass% or more and 15 mass% or less based on a mass of the toner. The C.I. Pigment Yellow 180 is plate-like particles having a plate-like shape. Upon observing the C.I. Pigment Yellow 180 using a scanning electron microscope, when a number average value of an equivalent circle diameter calculated from an area of a surface having a maximum area of the plate-like particles of the C.I. Pigment Yellow 180 is defined as S (nm), and a number average value of a width in a direction perpendicular to the surface having the maximum area of the plate-like particles of C.I. Pigment Yellow 180 is defined as Z (nm), the S and the Z satisfy S/Z≥10.0, 50≤S≤300.SELECTED DRAWING: None
【課題】優れた低温定着性を維持しながら、高温・高湿環境下においても高い帯電性を実現するイエロートナーの提供。【解決手段】結着樹脂、結晶性樹脂およびC.I.ピグメントイエロー180を含有するトナー粒子を有するイエロートナーであって、該C.I.ピグメントイエロー180は、トナーの質量を基準とした含有量が、3質量%以上15質量%以下であり、該C.I.ピグメントイエロー180は板状の形状を有する板状粒子であり、走査型電子顕微鏡を用いて該C.I.ピグメントイエロー180を観察したときの、該C.I.ピグメントイエロー180の板状粒子の最大面積を有する面の面積より算出される円相当径の個数平均値をS(nm)、C.I.ピグメントイエロー180の板状粒子の最大面積を有する面と直交する方向の幅の個数平均値をZ(nm)としたとき、該Sと該Zとが、S/Z≧10.050≦S≦300を満たすことを特徴とする。【選択図】なし |
