    摘要： A magnetic brush development station includes, a housing forming a reservoir for developer materials. A plurality of augers are located in the housing for mixing developer material. A development roller is mounted within the housing for delivering developer material from the reservoir to a development zone. The development roller includes a core magnet inside a shell, having relative rotation. The core magnet extends less than the entire length of the development roller such that a developer nap on the shell does not extend to the respective ends. A metering skive controls the quantity of developer material delivered from the reservoir. A metering skive is positioned parallel to a longitudinal axis of the development roller at a location upstream in the direction of shell rotation prior to the development zone. A magnetic seal is located in association with the skive at each end to substantially prevent leakage of developer material.

    摘要： A magnetic brush development station for a reproduction apparatus. The magnetic brush development station includes a housing forming, at least in part, a reservoir for developer material. The reservoir has a pressure equalization seal. A mechanism is associated with the housing for readily moving the housing relative to the reproduction apparatus. Another mechanism selectively readily replenishes and/or empties at least one component of developer material with respect to the reservoir. A plurality of augers are located in the housing for mixing developer material within the reservoir. A drive for the augers, extending through the housing, has a seal therefor. A development roller, mounted within the housing, delivers developer material from the reservoir to a development zone. The development roller includes a core magnet inside a shell such that the core magnet and the shell having relative rotation. The core magnet extends less than the entire length of the development roller such that the developer nap on the shell does not extend to the end of the development roller. A metering skive, extending the length of the development roller, controls the quantity of developer material delivered from the reservoir portion of the housing to the development zone. The metering skive is positioned parallel to the longitudinal axis of the development roller at a location upstream in the direction of shell rotation prior to the development zone. Further, a magnetic seal is located in association with the skive at each end of the development roller. The magnetic field of the magnetic seal is sufficient to substantially prevent leakage of developer material from the ends of the development roller.

    摘要翻译： 一种用于再现设备的磁刷显影站。 磁刷显影站包括至少部分地形成用于显影剂材料的储存器的壳体。 储存器具有压力均衡密封。 机构与壳体相关联，用于相对于再现设备容易地移动壳体。 选择性地容易地相对于储存器补充和/或排空显影剂材料的至少一种组分的另一机制。 多个螺旋钻位于壳体中，用于将显影剂材料混合在储存器内。 用于螺旋钻的驱动器延伸穿过壳体，具有密封件。 安装在壳体内的显影辊将显影剂材料从储存器传送到开发区。 显影辊包括在壳体内的芯磁体，使得芯磁体和壳体具有相对旋转。 芯磁体的延伸小于显影辊的整个长度，使得外壳上的显影剂打孔不延伸到显影辊的端部。 延伸显影辊的长度的计量滑板控制从壳体的储存部分传送到显影区的显影剂材料的数量。 在开发区之前，计量滑动件平行于显影辊的纵向轴线定位在外壳旋转方向上游的位置处。 此外，磁性密封件与显影辊的每个端部处的滑动件相关联地定位。 磁性密封的磁场足以基本上防止显影剂材料从显影辊的端部泄漏。
