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.

摘要： A developing unit used in an image forming apparatus with a latent image carrier includes a developer carrier, a supply compartment, a recovery compartment, a separation member, and a gap. The developer carrier facing the latent image carrier rotates while carrying two-component developer containing toner and carrier and supplies the toner to the latent image. The supply compartment includes a supply transport member to transport the developer in a first direction. The recovery compartment includes a recovery transport member to transport the developer in a second direction. The separation member includes one end portion facing the latent image carrier at a facing area. The separation member separates the supply compartment and the recovery compartment and is disposed above the recovery compartment behind the separation member.
