摘要： An image forming apparatus includes a toner image forming unit, a nip formation member, a transfer power source, an information acquisition device, and a controller. The information acquisition device acquires specific information that specifies whether a recording sheet as a transfer target of a toner image is an uneven surface sheet having an uneven surface. The controller outputs a bias including a superimposed voltage, in which an alternating current (AC) voltage is superimposed on a direct current (DC) voltage, as a transfer bias from the transfer power source when the specific information acquired by the information acquisition device is not information corresponding to the uneven surface sheet and to output a bias including only the DC voltage as the transfer bias from the transfer power source when the specific information is the information corresponding to the uneven surface sheet.

摘要： An image forming apparatus includes an image bearer, a detector, an image bearer support, and a fulcrum. The image bearer bears an image on a surface thereof. The detector detects a condition of the image bearer. The image bearer support supports the image bearer and includes a stopper to regulate movement of the detector. The fulcrum pivotally supports the image bearer and the detector.

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： 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.
