摘要:
A cleaning unit, providable to an image carrier unit or an image forming apparatus, includes a cleaning member disposed in contact with a target member to electrically remove residual toner from the target member, an elastic blade disposed in contact with the target member upstream from the cleaning member, a blade supporting member, a blade power source, and a conductive member that is more conductive than the elastic blade, and electrically connects the blade supporting member and the elastic blade. The conductive member is disposed so that an edge part of the conductive member is closer to where the elastic blade contacts the target member than an edge part of the blade supporting member.

A cleaning unit that can remove particles of residual toner remaining on an image carrier after transfer and be incorporated in a process cartridge removably installable to an image forming apparatus, includes a brush roller disposed in contact with the image carrier to remove the residual toner remaining on the image carrier from the image carrier, and a polarity control member disposed in contact with the image carrier to control charge polarities of the residual toner remaining on the image carrier before the residual toner is removed by the brush roller. The polarity control member includes a first surface where the polarity control member contacts the image carrier, a second surface where the polarity control member does not contact the image carrier, and a conductive filler that is not exposed on the first surface that contacts the image carrier.

摘要:
A brush roller includes conductive brush fibers and a conductive rotating shaft, and rotates around the rotating shaft so that the brush fibers make contact with a cleaning target to remove dirt from a surface of the cleaning target. A brush-roller cleaning unit makes contact with the brush fibers to remove the dirt from the brush fibers. A brush-fiber charge imparting unit makes contact with the brush fibers on a downstream side of a location where the brush-roller cleaning unit makes contact with the brush fibers and on an upstream side of a location where the brush fibers make contact with the cleaning target in rotation direction of the brush roller.
