摘要： A seamless intermediate transfer member has a reinforcing member in an endless configuration, a filler material such as a polymer and electrical property regulating material to regulate the electrical properties such as surface and bulk resistivity, dielectric constant and charge dissipation. The seamless intermediate transfer member also has good mechanical properties. The reinforcing member can be prepared by any suitable method such as by weaving. Filler material and electrical regulating material can be applied on, around or embedded into the reinforcing member. The member can be employed in an electrostatographic imaging system with more than one toner imaging station. The member can pick up a separate image from each individual imaging station and transfer the combined image to a suitable substrate. The seamless intermediate transfer member is capable of dissipating charge between toner imaging stations, achieving good transfer efficiencies and has a non-stretch characteristic to attain good registration of a toner image.

摘要： Electrostatographic coated carrier particles for use in the development of electrostatic latent images are provided by mixing carrier core materials with powdered thermoplastic resin particles having a size of between 0.1 micron and about 30 microns. The carrier core materials are mixed with the resin particles until the resin particles mechanically and/or electrostatically adhere to the core materials and the mixture is heated to a temperature of between 320.degree. F. and 650.degree. F. for between 120 minutes and 20 minutes so that the resin particles melt and fuse to the carrier core materials. The coated carrier particles are cooled, classified to the desired particle size, and mixed with finely-divided toner particles to form a developer mixture. The process is especially advantageous for coating carrier particles with resin materials having poor solubility characteristics.
摘要翻译：通过将载体芯材料与尺寸为0.1微米至约30微米的粉末状热塑性树脂颗粒混合来提供用于显影静电潜像的静电涂覆载体颗粒。载体芯材料与树脂颗粒混合，直到树脂颗粒机械和/或静电粘附到芯材上，并将混合物加热至320°F至650°F的温度，时间为120分钟至20分钟使树脂颗粒熔化并熔合到载体芯材料上。将涂覆的载体颗粒冷却，分级至所需的颗粒尺寸，并与细碎的调色剂颗粒混合以形成显影剂混合物。该方法对于用具有差的溶解度特性的树脂材料涂覆载体颗粒是特别有利的。

摘要： An image-bearing article used in liquid contact electrostatic printing (CEP) is formed from polymers that meet the requisite conformance and heat stability for the CEP process. Excessive absorption of toner carrier liquids by the image-bearing article in liquid CEP leads to the deterioration of the image-bearing article and reduces the useful life of the image-bearing article. The absorption of the toner carrier fluid may be controlled by the addition of oxides, silicone elastomers containing phenyl end groups, fluorosilicones or increasing the cross-linking density of the methyl silicones.
