    • A process for producing a toner by subjecting a polymer and a resin component containing a cross-linkable polymer capable of cross-linkingly reacting with the polymer, to cross-linking reaction in the presence of a first wax to form a wax-containing cross-linked polymer composition; mixing the wax-containing cross-linked polymer composition with at least a colorant and a second wax, followed by melt-kneading to form a toner composition; and pulverizing the toner composition to produce toner particles. Also disclosed is a toner produced by this process. The toner thus obtained is a toner whose fixing performance and anti-offset properties are well balanced and also which makes it possible to afford images having less fog and high quality, over a long period of time in environments of from low temperature and low humidity to high temperature and high humidity, and is highly durable without causing any contamination of members with which the toner comes into contact.
    • 通过使含有能够与聚合物交联反应的交联性聚合物的聚合物和树脂成分在第一蜡的存在下进行交联反应而形成含蜡交联剂来制造调色剂的方法, 连接聚合物组成; 将含蜡的交联聚合物组合物与至少一种着色剂和第二种蜡混合,然后熔融捏合以形成调色剂组合物; 并粉碎调色剂组合物以产生调色剂颗粒。 还公开了通过该方法生产的调色剂。 由此获得的调色剂是其定影性能和抗污损性能良好平衡的调色剂,并且还使得可以在低温和低湿度的环境中长时间地提供具有较少雾度和高质量的图像, 耐高温和高湿度,并且高度耐用,而不会引起调色剂接触的部件的任何污染。
