Abstract: A cleaning device includes a cleaning unit and a movement mechanism. The cleaning unit includes: a cleaning part that has a contact surface extending along an axial direction of the conveyance roller and cleans the surface of the conveyance roller by bringing the contact surface into contact with the surface of the conveyance roller from below, and a cleaning housing that supports the cleaning part. The movement mechanism moves the cleaning unit between a cleaning position and a mounting and removing position below the cleaning position. The movement mechanism allows the cleaning part to be brought into contact with the conveyance roller at the cleaning position, allows the cleaning part to be disposed below the conveyance roller in a separated manner at the mounting and removing position and allows the cleaning unit to be mounted on or to be removed from an apparatus body.

Abstract: A cleaning device includes a separation and contact mechanism and a controller. The controller includes a separation and contact control unit, a conveyance roller rotation control unit, and a take-up control unit. The separation and contact control unit controls the separation and contact mechanism so as to allow the web to be pressed to the conveyance roller when the conveyance roller is in a non-conveyable state. The conveyance roller rotation control unit rotates the conveyance roller at a cleaning rotational speed lower than a conveyance-time rotational speed of the conveyance roller in a conveyance state. The take-up control unit allows the take-up roller to perform a take-up operation of taking up the web corresponding to a rotation of a take-up roller plural times at a predetermined time interval within a cleaning time in a state where the conveyance roller is being rotated at the cleaning rotational speed.

Abstract: A cleaning device includes a cleaning unit which removes foreign matter adhered on a conveyance face of a conveyance member conveying a sheet, by using a belt shaped web; and a unit moving mechanism which displaces the cleaning unit to a cleaning position where the cleaning unit comes into contact with the conveyance face and to a separation position separated away from the cleaning position. The cleaning unit includes a delivery roller delivering the web, a pressure roller bringing the web pressure-contact with the conveyance face and a winding roller winding the web passed the conveyance face. The cleaning unit is tilted such that a cleaning face of the web between the pressure roller and the winding roller faces upward as the cleaning unit is displaced from the cleaning position to the separation position.

Abstract: The cleaning device includes a cleaning unit. The cleaning unit includes a cleaning part having a contact surface brought into contact with a surface of a conveyance roller to clean the surface of the conveyance roller, and a housing that supports the cleaning part. The cleaning part includes a web of a strip shape, the web forming the contact surface that comes in contact with the conveyance roller, a pressing roller that presses the web against the conveyance roller, a feed-out roller that feeds out the web so as to cause a part of the web that comes in contact with the conveyance roller to shift, and a take-up roller that takes up the web. The housing has an opening that receives foreign matter dropping from the vicinity of a nip portion formed between the pressing roller and the conveyance roller.

Abstract: A cleaning device includes a cleaning unit, a movement mechanism, and a unit mounting portion. The cleaning unit includes a cleaning part having a contact surface brought into contact with a surface of a conveyance roller. The movement mechanism moves the cleaning unit between a cleaning position at which the cleaning part comes in contact with the conveyance roller, and a mounting and removing position at which the cleaning part is located below the conveyance roller in a separated manner and the cleaning unit is allowed to be mounted and removed on and from the apparatus body. The unit mounting portion houses the cleaning unit disposed at the mounting and removing position. The cleaning unit is configured such that the cleaning unit in a state of being housed in the unit mounting portion is mounted and removed, together with the processing unit, on and from the apparatus body.

Abstract: A cleaning device includes a controller configured to control cleaning of a conveyance roller by a web. The controller includes a take-up control unit and a web end determination unit. The take-up control unit controls the solenoid such that the web is taken up by rotatably driving the take-up roller in a state where the web is pressed to the conveyance roller. The web end determination unit determines whether or not an end of the web is exposed on a support roller by a take-up operation of the take-up roller. The web end determination unit determines that the end of the web is exposed on the support roller when a detection result of a detection unit is not changed in spite of a fact that supplying of electricity to the solenoid is performed.

Abstract: A cleaning device includes a sheet conveyance roller, and a cleaning unit that cleans a surface of the sheet conveyance roller. The cleaning unit includes a cleaning member that can come in contact with the surface of the sheet conveyance roller, and a pressing roller that presses the cleaning member against the surface of the sheet conveyance roller. The pressing roller includes a low Young's modulus area formed at least on a part of the pressing roller in a radial direction, the low Young's modulus area having a Young's modulus lower than a Young's modulus of the sheet conveyance roller. When the surface of the sheet conveyance roller is cleaned, the pressing roller is pressed against the sheet conveyance roller so as to elastically deform in the radial direction in a state where the cleaning member is sandwiched between the pressing roller and the sheet conveyance roller.
