摘要： A contaminant removing member for removing contaminants adhering to the surface of the photoconductive member is contacted to and pressed against the surface of the photoconductive member by an engaging and disengaging mechanism only when a contaminant removing operation is performed. Accordingly, the contaminants adhering to the surface of the photosensitive drum can be removed while damage to the surface of the photosensitive drum is minimized. Alternatively the contaminant removing operation can be performed by a contaminant removing member removably mounted to one of a toner container or a photosensitive member container.

摘要： An image forming apparatus includes: a belt having a carrying surface that carries a recording sheet; a photosensitive body disposed opposite to the carrying surface of the belt; a transferring member which is disposed opposite to the photosensitive body such that the carrying surface of the belt is disposed between the transferring member and the photosensitive body, and a transferring bias is applied to the transferring member; a cleaning member arranged adjacent to an outer peripheral surface of the belt; and a control unit for controlling a voltage that is applied to the cleaning member. The control unit causes a first voltage to be applied to the cleaning member during a first mode. The control unit causes a second voltage, different from the first voltage, to be applied to the cleaning member during a second mode.

摘要： An image forming device capable of sufficiently removing paper dusts on a sheet thereby providing high quality image. A sheet transport path 38 is defined between a sheet supply section 7 provided with a separation pad 13 and a sheet supply roller 12 and an image forming section 5. Along the sheet supply section 7, at least a first paper dust removing roller 9b having a width slightly greater than the width of the separation pad 13 and a second paper dust removing roller 10b having a width slightly greater than the sheet width are disposed. Paper dusts generated upon friction against the separation pad 13 are removed by the first paper dust removing roller 9b, and paper dusts spreading over entire surface of the sheet are removed by the second paper dust removing roller 10b.

摘要： A belt cleaning device includes a cleaning roller, a backup roller, and a roller-pressing-state setting mechanism. The cleaning roller is disposed in confrontation with a surface of a belt. The backup roller is disposed in confrontation with the cleaning roller with the belt interposed between the cleaning roller and the backup roller. The roller-pressing-state setting mechanism selectively sets a state of the backup roller to a first state in which the backup roller is pressed against the cleaning roller via the belt, allowing a first pressure to be applied between the cleaning roller and the surface of the belt, and a second state in which a second pressure is applied between the cleaning roller and the surface of the belt. The second pressure is less than the first pressure.
