摘要： A magnetic brush development station for developing latent image charge patterns supported on a moving image support member of an electrostatographic reproduction apparatus. The magnetic brush development station includes a housing located in operative association with an extended run of the image support member. The housing has a portion constituting a sump for developer material, and a portion defining an opening facing the image support member. Further, the magnetic brush development station includes an applicator for applying developer material to a latent image charge pattern on the image support member to develop such latent image charge pattern. The applicator includes a sleeve located in the last mentioned portion of the housing, above the developer material sump, the sleeve having a development surface operatively associated with the image support member through the opening and configured to complementarily conform to the run of the image support member to define an extended uniform development zone. A plurality of rotatable magnets are located adjacent to the underside of the development surface of the sleeve to move developer material through the development zone.
摘要翻译：一种磁刷显影台，用于显影支持在静电图像再现装置的运动图像支持部件上的潜像电荷图案。磁刷显影台包括与图像支撑构件的延长运行有效关联的壳体。壳体具有构成用于显影剂材料的贮槽的部分和限定面向图像支撑构件的开口的部分。此外，磁刷显影台包括用于将显影剂材料施加到图像支撑构件上的潜像电荷图案上以形成这种潜像电荷图案的施加器。施加器包括位于壳体的最后提到的部分中的套筒，位于显影剂料槽之上，套筒具有通过开口与图像支撑构件可操作地相关联的显影表面，并且构造成与图像支撑构件的运行互补地一致定义一个扩展的统一开发区。多个可旋转磁体位于套筒的显影表面的下侧附近以将显影剂材料移动通过显影区。

摘要： In an electrostatographic reproduction apparatus utilizing a dielectric member web supported by guide rollers for movement along a travel path in relation to electrostatographic process stations, including a web cleaning station, a web cleaning assembly is mounted so that it operates effectively to remove residual marking particles from the web without adversely effecting web tracking as it moves along its desired travel path. In a preferred embodiment of this invention, the cleaning assembly comprises a housing including a chamber adapted to store removed residual marking particles, and a member engaging the web to break the bonds between the residual marking particles and the web for sweeping such particles from the web into the chamber. The housing is mounted relative to one of the guide rollers for movement therewith as such guide roller guides the web along the desired travel path, and with the sweeping member in operative association with the web.

摘要： Controlling the charge on toner in a development station of an electrographic reproduction apparatus, wherein data relative to latent image charge carrying member voltage and image density control patches are sensed and development potential to achieve an aim density is calculated therefrom. A delta from an optimum development potential range is calculated, and in response to the determined delta, an amount of liquid charge control agent, from a supply of suitable liquid charge control agent, necessary to be added to the developer material in the development station to bring the toner to substantially a charge level that will enable a desired optimum developer potential is calculated. The calculated amount of liquid charge control agent is then injected directly into the development station.
