摘要: Magnetite particles having an average particle diameter of 0.05 to 0.50 µm, and having a plurality of rounded protrusions on the surface of each particle, the number of protrusions being from 2 to 30 when viewed in projected plan and process for producing the particles.
Magnetic iron oxide particles comprising at least 60% in number of the magnetite particles are useful in a magnetic toner.摘要翻译: 具有上的0:05平均粒径为0:50微米,以及具有圆形突起的多元性磁铁矿颗粒是每个颗粒的表面上,突起的数目是从2为〜30。当在投影平面和用于生产所述颗粒被观看。 在磁铁矿颗粒的数目,其包含至少60%的磁性氧化铁颗粒在磁性调色剂是有用的。
