A belt rotating device includes a belt wound around plural rollers to circulate and move, the plural rollers including a roller to be cleaned; and a first cleaning unit disposed inside the belt, the first cleaning unit being in contact with at least the roller to be cleaned to scrape off foreign matter on the roller to be cleaned, the first cleaning unit being configured to change a contact state with respect to the roller to be cleaned.

Belt rotating device with cleaning device and image forming apparatus

An image forming apparatus includes an image bearing member having an inorganic protective layer on a surface thereof, a cleaning blade having an inclined surface cut out at a corner portion on a side of the image bearing member, and a support portion that supports the cleaning blade so that the inclined surface is in contact with the image bearing member.

Image forming apparatus

An image forming unit includes an image carrying body, a plate-shaped cleaning member, and a powder of a fatty acid metal salt. The image carrying body is configured to be rotatable and carries an image formed on a surface thereof with a toner. The plate-shaped cleaning member includes a tip portion which is pressed against the surface and which scrapes a material adhering onto the surface in response to rotation of the image carrying body. The powder of the fatty acid metal salt is applied to at least one of the tip portion and the surface.

Image forming unit, image forming apparatus, and cleaning device

A cleaning member includes a body and an edge. The body has rubber hardness of about 68 to 75 degrees and is fixed to a support member at one end of the body. The body has a plate-like shape in which a corner portion of the body is missing. The edge is provided at the corner portion and fits into it. The edge is in contact with a subject to be cleaned and has a thickness of about 0.1 to 1 mm. The cleaning member satisfies the following conditions:80&#x2266;&#x2266;90;&#x2267;&#x2212;40+95; and&#x2266;&#x2212;40110where x denotes a ratio of a length of the edge in a predetermined direction to a length of a portion of the body which is not fixed to the support member in the predetermined direction, and y denotes rubber hardness of the edge.

Developing device and image forming apparatus including cleaning member and cleaning member

A cleaning blade includes a portion which comes in contact with a member to be cleaned, and the portion is configured of a member containing polyurethane rubber having a structure derived from polyester polyol in which a first diol component having 10 or more carbon atoms and a second diol component having 5 or less carbon atoms are condensed with dicarboxylic acid at a molar ratio (first diol component/second diol component) of 50/50 to 80/20, a structure derived from polyisocyanate, and a structure derived from a triol.

Cleaning blade, cleaning device, and image forming apparatus

A cleaning device includes a developer removing member with one long-side edge thereof coming into contact with an image carrier, a supporting member supporting the developer removing member such that the developer removing member extends beyond the supporting member on a side thereof having the one long-side edge, a developer collecting member having an opening for collecting developer residues and configured such that the one long-side edge of the developer removing member is positioned in a short-side central portion of the opening and portions defining one long-side edge and two short-side edges of the opening face a combination of the supporting member and the developer removing member, a sealing member provided between the combination and the portions defining the one long-side edge and the two short-side edges of the opening, and an adhesion preventing member interposed between the sealing member and the developer removing member.

Cleaning device and image forming apparatus

A cleaning device includes a residual-toner accommodation housing having an opening facing toward a post-transfer area of a toner-image bearing member and surrounded by first and second edges and two connecting edges; a residual-toner removing member that overlies the first and connecting edges, has an edge protruding above the opening and abutting on the bearing member, and scrapes off toner from the bearing member toward the housing; a thermoplastic seal member intervening the housing and removing member, having terminal end portions extending along the connecting edges and protruding from the edge, and extending along the first and connecting edges to prevent the toner from leaking through a gap between the housing and removing member; and a sheet-like seal member that covers the second edge, is in contact with the bearing member, and intervenes the bearing member and terminal end portions to prevent the scraped-off toner from leaking from the housing.

An image forming apparatus includes a body, a developer recovery container, a detecting section, a power supply, a detection object part, a pair of wires, a conducting section, a drive section, and a determining section. The determining section determines the developer recovery container to have been used in a case where the developer is determined to be not present in the detection object part on the basis of information from the detecting section, and in a case where the developer is determined to be present in the detection object part, checks the information from the detecting section again after driving the drive section, and determines the recovery container to have not been used when the developer is determined to be not present in the detection object part and determines the recovery container to have been used when the developer is determined to be present in the detection object part.

Image forming apparatus, image forming system, and computer readable medium

A cleaning device includes a cleaning blade member that has a tip abutting a surface of an image carrier so as to remove a residue remaining on the surface of the image carrier; an attaching member that includes a first attachment piece to which a base end of the cleaning blade member is attached, and a second attachment piece which is provided so as to intersect the first attachment piece at a predetermined angle; a housing member to which one of the first attachment piece and the second attachment piece is fixed at both ends along a longitudinal direction thereof; and an external force exerting member that exerts an external force in a direction which intersects a surface of the other one of the first attachment piece and the second attachment piece, which is not fixed to the housing member.

Cleaning device and image forming apparatus using the same

A cleaning device includes a cleaning blade that contacts a surface of a member to be cleaned to remove a residue remaining on the surface of the member to be cleaned, and that includes multiple layers, wherein a leading end portion of the cleaning blade shifts in a separating direction from the surface of the member to be cleaned due to a difference in thermal expansion property among the multiple layers when temperature rises.

A cleaning member includes a cleaning part whose one end portion comes into contact with a surface of an image carrier, and a supporting part that supports the cleaning part and applies a force for pressing the one end portion of the cleaning part to the surface of the image carrier, wherein a surface of a first portion including the one end portion of the cleaning part is bonded to the supporting part with a first adhesive layer, and a surface of a second portion including the other end portion opposite to the one end portion of the cleaning part is bonded to the supporting part with a second adhesive layer having a Type-A durometer hardness which is lower than that of the first adhesive layer.
