An image forming apparatus includes a first image forming portion, a second image forming portion, a belt, a charging voltage applying portion, and a transfer voltage applying portion. With respect to a movement direction of a recording material, the first image forming portion is provided upstream of the second image forming portion. In an image forming operation, a potential difference between a first transfer voltage and a potential at a first transfer portion, which is formed on a first image bearing member and does not form the image, is greater than a potential difference between a second transfer voltage and a potential at a second transfer portion, which is formed on a second image bearing member and does not form an image.

Novel materials and devices can remove small defects from long rolls of flexible electronics material while they are in continuous motion. The cleaning materials are designed to remove small particles without transferring defects or damaging the flexible electronics. The device generally consists of variable speed, motor-driven cylinders mounted on moveable brackets. The cylinders are capable of matching the speed of the cleaning material such that the cleaning material is always in contact with the web roll to be cleaned. The brackets are capable of rotating so the same material can be used more than once. Another material is used to remove debris from the cleaning material. A similar device consisting of motor-driven cylinders and moveable is used to apply the debris removal film to the cleaning film, allowing the cleaning film to be used multiple times.

An example cleaning station for a liquid electrophotographic printer is described. The cleaning station has a first cleaning member, a second cleaning member, and a biasing member. The cleaning station is configured to move between a first position and a second position with respect to a photo imaging member of the printer. In the first position, the first cleaning member is arranged to remove particles from the photo imaging member of the printer and the second cleaning member is arranged to apply a force to a layer of liquid applied to the photo imaging member. In the second position, the biasing member is configured to cause the second cleaning member to contact the first cleaning member to clean the second cleaning member.

A cleaning solution is used to at least substantially remove colorant from the photoconductive drum as the photoconductive drum rotates. A wiper wipes the cleaning solution from the photoconductive drum while purposefully maintaining a layer of the cleaning solution on the drum. The wiper has an edge that is purposefully rounded.

A cleaning device for a surface of a cylinder of a printer and/or a copier includes a cylindrical cleaning element which can be rotated by at least one drive and which includes a cleaning fitting on its outer periphery, and a suction or suctioner conducting at least one suction medium with at least one suction channel aligned towards the outer periphery of the cleaning element and extending along the longitudinal alignment of the cleaning element. In order to achieve a simple technical structure and a low maintenance effort apart from a good cleaning result and reliable dirt removal, a suction slit extending longitudinally of the suction channel is aligned towards the cleaning element opens into the suction channel tangentially to the suction channel cross section.

A cleaning pad can be attached onto an inner surface of a transport belt so the cleaning pad can move with the transport belt along hardware of a marking system, including support rollers and a marking platen to remove ink from the marking platen and support rollers of the rendering device as the transport belt cycles through its typical path within the rendering system.

An image forming apparatus includes a photoconductor drum, a developing roller, a first shaft provided for one of the photoconductor drum and the developing roller, a second shaft provided for the other of the photoconductor drum and the developing roller, a first housing supporting the first shaft, and removable in an axial direction of the first shaft, a second housing supporting the second shaft, and removable in an axial direction of the second shaft, a first contact member provided on an axial end portion of the first housing, a second contact member provided on an axial end portion of the second housing, and located in contact with the first contact member, a first cover covering the first contact member, and a first cleaning device provided on the first cover, and configured to rub against the second contact member, when the second housing is inserted or removed.

The present disclosure relates to an electrophotographic printer comprising a photoconductive cylinder, and a cleaning element comprising an absorbent foam substrate. The absorbent foam substrate has an abrasive material disposed on at least an outer surface of the absorbent foam substrate. At least part of the outer surface of the absorbent foam substrate is engageable with the photoconductive cylinder.

A cleaning device that cleans a surface of an image holding unit capable of holding an image formed using an image forming material includes: a cleaning tool that is movable along an intersecting direction intersecting with a moving direction of the image holding unit and cleans the surface of the image holding unit when placed in a contact position where the cleaning tool is in contact with the surface of the image holding unit; and a guiding unit that guides the cleaning tool so that the cleaning tool moves from a non-contact position where the cleaning tool is not in contact with the image holding unit to the contact position for cleaning the surface of the image holding unit, wherein when the image holding unit is moved, the cleaning tool placed in the contact position cleans the surface of the image holding unit.
