US08787804B2 Developing device including a developer container with toner particles and magnetic carrier particles (Rz=0.5−3.0 gm) and a developer bearing member (Rz=10−30 gm), and an image forming apparatus and process cartridge containing the same 有权
显影装置包括具有调色剂颗粒和磁性载体颗粒（Rz = 0.5-3.0gm）和显影剂承载构件（Rz = 10-30gm）的显影剂容器，以及包含其的成像设备和处理盒

Developing device including a developer container with toner particles and magnetic carrier particles (Rz=0.5−3.0 gm) and a developer bearing member (Rz=10−30 gm), and an image forming apparatus and process cartridge containing the same
Abstract:
A developing device including a developer container and a developer bearing member is provided. The developer container contains a two-component developer comprising toner particles and magnetic carrier particles having a ten-point average surface roughness Rz of 0.5 to 3.0 μm. The developer bearing member is a cylindrical member containing a magnetic field generator having multiple magnetic poles. The developer bearing member is adapted to bear the two-component developer on a surface thereof and to convey the two-component developer as the surface rotates. The developer bearing member has a ten-point average surface roughness Rz of 10 to 30 μm. The multiple magnetic poles include three developer bearing poles each adapted to generate a magnetic field having a strength enough for retaining the two-component developer on a surface of the developer bearing member. The three developer bearing poles consist of a developing pole, a pre-developing pole, and a post-developing pole.
Abstract(Chinese):

提供了包括显影剂容器和显影剂承载部件的显影装置。 显影剂容器含有包含调色剂颗粒和磁性载体颗粒的双组分显影剂，其十点平均表面粗糙度Rz为0.5-3.0μm。 显影剂承载构件是包含具有多个磁极的磁场发生器的圆柱形构件。 显影剂承载构件适于在其表面上承载双组分显影剂并且在表面旋转时输送双组分显影剂。 显影剂承载部件的十点平均表面粗糙度Rz为10〜30μm。 多个磁极包括三个显影剂承载极，每个显影剂承载极适于产生具有足以将双组分显影剂保持在显影剂承载部件的表面上的强度的磁场。 三个显影轴承杆由一个显影极，一个前显影极和一个后显影极组成。
