摘要： An electrophotographic toner is formed as a blend of toner particles and external additives. The external additives include (1) first inorganic fine particles having an average primary particle size of 80-800 nm of oxide of a metal selected from the group consisting of titanium, aluminum, zinc and zirconium, (2) second inorganic fine particles other than silica having an average primary particle size of below 80 nm and (3) silica fine particles having an average primary particle size of below 30 nm. As a result, the toner can be made free from difficulties, such as melt-sticking onto an image-bearing member in a low humidity environment, roughening of halftone images in a low humidity environment, toner blot-down after storage at high temperatures or in continuous image formation on a large number of sheets, fog in continuous formations of images of low color area percentage in a low humidity environment, and retransfer in multi-color image formation. Thus, the toner is suitably used in a multi-color image forming system.
摘要翻译：作为调色剂颗粒和外部添加剂的混合物形成电子照相调色剂。外部添加剂包括（1）选自钛，铝，锌和锆的金属的氧化物的平均一次粒径为80-800nm的第一无机细颗粒，（2）除了钛，铝，锌和锆之外的第二无机细颗粒平均一次粒径小于80nm的二氧化硅和（3）平均一次粒径小于30nm的二氧化硅微粒。结果，可以使调色剂不受困扰，例如在低湿度环境下熔融粘附到图像承载部件上，在低湿度环境下对半色调图像进行粗糙化，在高温下储存后的调色剂印迹下降;或在大量片材上连续成像时，在低湿度环境下连续形成低色彩区域图像的图像，并且在多色图像形成中重新转印。因此，调色剂适用于多色成像系统。

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.
