用于静电潜像显影的调色剂、其生产方法和使用其的静电潜像显影剂
摘要：
本发明提供了一种用于使静电潜像显影的调色剂，其包含调色剂颗粒，该调色剂颗粒至少包含粘合剂树脂、着色剂和脱模剂；其中该调色剂颗粒的体积平均粒径为约5～8μm；调色剂颗粒的形状因子SF1平均值为约125～140；调色剂颗粒表面的算术平均起伏高度在其累积分布曲线上的90%点处的值为约0.15～0.25μm。此外，本发明提供了一种包含该调色剂的静电潜像显影剂。本发明还提供了生产该调色剂的方法。
摘要（英）：

The present invention provides a toner for developing an electrostatic latent image comprising of: toner particles containing at least a binder resin, a colorant and a releasing agent; wherein a volume-average particle diameter of the toner particles is in a range of about 5 to 8 mum; an average of shape factor SF1 of the toner particles is in a range of about 125 to 140; and an arithmetical meanundulation height of the surface of the toner particles at the 90% point on the cumulative distribution curve is in a range of about 0.15 to 0.25 mum. Further, the present invention provides an electrostatic latent image developer containing the toner. The invention also provides a method for producing the toner.
