    • A developing device including a developer bearing member containing a magnetic field generator having multiple magnetic poles and a developer containing chamber is provided. The developer containing chamber contains a two-component developer comprising magnetic carrier particles having a saturated magnetization of 58 to 70 emu/g in a magnetic field of 1 KOe and toner particles, and has a divider to define an upper supply chamber and a lower collection chamber. The supply chamber includes a supply conveyer to supply the two-component developer to the developer bearing member at an upstream side from the developing area. The collection chamber includes a collection conveyer to collect the two-component developer from the developer bearing member at a downstream side from the developing area. The multiple magnetic poles includes three developer bearing poles capable of bearing the developer on its surface.
    • 提供一种显影装置,其包括含有具有多个磁极的磁场发生器和显影剂容纳室的显影剂承载部件。 显影剂容纳室包含双组分显影剂,其包括在1KOe的磁场中具有58至70emu / g的饱和磁化强度和调色剂颗粒的磁性载体颗粒,并且具有分隔件以限定上部供应室和下部集合体 房间。 供给室包括供给输送器,用于在显影区域的上游侧将双组分显影剂供应到显影剂承载部件。 收集室包括收集传送器,用于在显影区域的下游侧从显影剂承载部件收集双组分显影剂。 多个磁极包括能够在其表面上承载显影剂的三个显影剂承载杆。
