CN106154775B 静电图像显影用调色剂、静电图像显影剂、以及调色剂盒 有权

静电图像显影用调色剂、静电图像显影剂、以及调色剂盒
Abstract:
本发明提供一种静电图像显影用调色剂，包含：调色剂颗粒，该调色剂颗粒含有：包含聚酯树脂的粘结剂树脂；包含烃蜡的防粘剂；以及苯乙烯(甲基)丙烯酸树脂，其中70％以上的防粘剂存在于距所述调色剂颗粒的表面的800nm以内，并且所述调色剂颗粒中的苯乙烯(甲基)丙烯酸树脂形成平均直径为0.3μm至0.8μm的结构域，并且在平均直径的±0.1μm范围内的结构域的数量比为65％以上。本发明还提供一种静电图像显影剂、以及调色剂盒。即使在高温高湿下形成低密度图像之后，形成高密度图像时，该静电图像显影用调色剂也能防止极光现象的发生。
Abstract(English):

An electrostatic charge image developing toner, includes toner particles containing a binder resin including a polyester resin, a release agent including a hydrocarbon wax, and a styrene (meth)acrylic resin, wherein 70% or more of the release agent is present within 800 nm from a surface of the toner particles, the styrene (meth)acrylic resin in the toner particles forms a domain having an average diameter from 0.3 μm to 0.8 μm, and a number ratio of the domain being in a range of ±0.1 μm of the average diameter is 65% or more.
