摘要:
At a carriage that shows a resonance mode in opposite phase to a resonance mode shown by a plate table where an interferometer which measures a position (a first controlled variable) of a plate stage driven according to a control input is installed, another interferometer is installed which measures a position (the second controlled variable) of the plate stage. By using the interferometer and the another interferometer, it becomes possible to design a driving system robust in a high bandwidth that drives the plate stage.

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.
