    摘要： An image forming apparatus includes a belt-shaped image bearer; a transfer device disposed opposing to the image bearer; an opposed device disposed opposing to the transfer device; and a transfer bias power source. The image bearer is disposed along an outer circumferential surface of the transfer device at least one of an upstream side and a downstream side of the transfer portion in a direction of conveyance of the recording medium. The transfer bias power source cyclically alternates the transfer bias applied to the transfer portion, between a transfer directional bias in a transfer direction to transfer the toner image from the image bearer onto the recording medium and a reverse directional bias in a reverse direction of the transfer direction. The transfer bias power source applies the reverse directional bias during a time period longer than 50% of one cycle of the applied transfer bias in the one cycle.

    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.

    摘要： A cleaner includes a cleaning member electrostatically removing toner on an object; a first electricity supplier supplying a first voltage (or current) with polarity opposite to that of toner to the cleaning member; a toner collecting member collecting toner from the cleaning member; and a second electricity supplier supplying a second voltage with the polarity greater than the first voltage to the toner collecting member. The first and second electricity suppliers set plural setting values of the first and second voltages smaller than the targeted values of the first and second voltages, and first and second control members of the first and second electricity suppliers output first and second control signals while changing in step-by-step manner so that first and second output members of the first and second electricity suppliers apply the first and second voltage in step-by-step manner before the first and second voltages reach the targeted voltages.
