摘要： A cleaning device includes a plurality of cleaners. The plurality of cleaners includes at least a first cleaner, a second cleaner, and a third cleaner arranged next to each other in a traveling direction of a cleaning target. The first cleaner is disposed at an extreme upstream end of the traveling direction and supplied with a first voltage having a same polarity as a polarity of a normally-charged toner. The cleaners, other than the first cleaner, disposed downstream from the first cleaner, is supplied with a second voltage having a polarity opposite the polarity of the normally-charged toner.

摘要： An image forming apparatus comprises a rotatable image bearer, a toner image forming device, a transfer device, a transfer bias power source, and a cleaner. The toner image forming device is to form a toner image on the image bearer. The transfer device contacts a surface of the image bearer to form a transfer nip between the transfer device and the image bearer. The transfer bias power source is to output a transfer bias to transfer the toner image from the image bearer onto a recording medium in the transfer nip. The cleaner is disposed downstream from the transfer nip in a direction of rotation of the image bearer, to electrostatically attract and remove toner from the surface of the image bearer to a surface of the cleaner. The transfer bias includes an alternating current component.
