摘要： A developing device includes a developer bearer and a regulation member. The developer bearer bears developer on a surface thereof. The developer bearer is rotatable forward and in reverse. The regulation member is disposed in contact or non-contact with the surface of the developer bearer to regulate amount of the developer on the developer bearer. In a non-development period, when the developer bearer rotates in a direction of reverse rotation opposite to a direction of forward rotation in which the developer bearer rotates in a development period, the developer bearer stops a series of rotating operations after the developer bearer rotates in the direction of forward rotation as a last rotating operation. A total rotation amount of forward rotation is set to be greater than a total rotation amount of reverse rotation in the series of rotating operations.

摘要： An image forming apparatus capable of maintaining cleaning performance of a cleaning brush and downsizing the apparatus main body. Transfer residual toner accumulated on the cleaning brush is transferred onto a photoreceptor by an electrostatic force, hence the cleaning brush becomes clean and the cleaning performance thereof improves. Therefore, the photoreceptor and a charging roller can be cleaned well by the cleaning brush over a long period of time, and the photoreceptor can be charged well by the charging roller over a long period of time. Moreover, because the transfer residual toner that is transferred from the cleaning brush onto the photoreceptor is recovered by a developing device, it is not necessary to provide the apparatus main body with a toner recovery portion that is specially designed for recovering the transfer residual toner, hence the apparatus main body can be downsized.
摘要翻译：一种能够保持清洁刷的清洁性能并且使装置主体小型化的图像形成装置。转印在清洁刷上的转印残留调色剂通过静电力转印到感光体上，清洁刷变清洁，清洗性能提高。因此，可以通过清洁刷长时间清洁感光体和充电辊，并且可以通过充电辊在长时间内充分地对感光体充电。此外，由于通过显影装置回收从清洁刷转印到感光体上的转印残余调色剂，所以不必为设备主体提供专门设计用于回收转印残留调色剂的调色剂回收部分，因此能够使装置主体小型化。
