摘要： A non-magnetic mono-component toner of the present invention is composed of a coloring powder at least containing a binder resin, coloring agent and wax and at least one kind of external additive having a mean particle diameter of 0.04 μm or greater, wherein the relationship between the Vickers hardness of the above coloring powder and the mean particle diameter of the external additives satisfies the predetermined expression. Thereby, the present invention is effective in preventing the external additive particles from sinking into the toner surface as well as from falling off from the surface when the toner particles are stressed in the developing unit. As a result, it is possible to provide stable image quality free from degradation of toner charge performance and toner supply performance even for long-term use.
摘要翻译：本发明的非磁性单组分调色剂由至少含有粘合剂树脂，着色剂和蜡的至少一种平均粒径为0.04μm以上的外部添加剂的着色粉末组成，其中，上述着色粉末的维氏硬度与外部添加剂的平均粒径之间的关系满足规定的表达式。因此，本发明在调色剂颗粒在显影单元中被应力时有效地防止外部添加剂颗粒沉入调色剂表面以及从表面脱落。结果，即使长期使用也可以提供稳定的图像质量，而不会降低调色剂充电性能和调色剂供应性能。
