摘要： A toner for developing an electrostatic image is formed of toner particles; wherein each toner particle includes (i) 100 wt. parts of a binder resin having a glass transition point (Tg) of 50-70° C., (ii) 0.2-20 wt. parts of solid wax, and (iii) colorant particles or magnetic powder; (iv) lubricant particles carrying a liquid lubricant, so that the toner particle retains at its surface the liquid lubricant gradually released from the particles (iv). The toner may be further blended with an organically treated inorganic fine powder to provide a developer. The toner or developer retains good lubricity and releasability so that it is suitable to be used in an image forming method including means contacting a latent image-bearing means, such as a contact charging means, a contact transfer means or a contact cleaning means.
摘要翻译：用于显影静电图像的调色剂由调色剂颗粒形成; 其中每个调色剂颗粒包括（i）100重量％玻璃化转变点（Tg）为50-70℃的粘合剂树脂的部分，（ii）0.2-20重量％部分固体蜡，和（iii）着色剂颗粒或磁性粉末; （iv）携带液体润滑剂的润滑剂颗粒，使得调色剂颗粒在其表面保留液体润滑剂从颗粒（iv）逐渐释放。调色剂可以进一步与有机处理的无机细粉混合以提供显影剂。调色剂或显影剂保持良好的润滑性和脱模性，因此适合用于图像形成方法，包括使潜像承载装置（例如接触充电装置，接触转印装置或接触清洁装置）接触的装置。

摘要： A toner for developing an electrostatic image is provided as a pulverized mixture including a binder resin and a colorant. The binder resin is characterized by a molecular weight distribution on a GPC chromatogram of its tetrahydrofuran (THF)-soluble resin content including below 15% of a resin component in a molecular weight region of at most 5000 and at least 5 wt. % of a resin component in a molecular weight region of at least 5.times.10.sup.6 and showing a main peak in a molecular weight region of 5000 to 5.times.10.sup.6. The THF-soluble resin component in the molecular weight region of at least 5.times.10.sup.6 is extremely enriched during a melt-kneading step during the toner production, so as to effectively prevent toner flowout from a member for cleaning a fixing roller.
