摘要： A binder resin as the main component of the toner has a low molecular weight polypropylene as a separating agent, encapsulated therein. Using this binder a toner with the wax having a diameter of 0.3 .mu.m or less dispersed therein is produced. The wax is included 0.5 part to 5 parts by weight for 100 parts by weight of the binder resin. This limitation of the toner prevents the setoff phenomenon during the fixing process and at the same time prevents the filming phenomenon over the photoreceptor and achieves an improved fixing performance.
摘要翻译： 作为调色剂的主要成分的粘合剂树脂具有作为分离剂的低分子量聚丙烯，被封装在其中。 使用该粘合剂制造分散有直径为0.3μm以下的蜡的调色剂。 对于100重量份的粘合剂树脂，蜡包含0.5重量份至5重量份。 调色剂的这种限制防止了定影过程中的咬合现象，并且同时防止了感光体上的成膜现象并且实现了改进的定影性能。
