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.

Abstract: A cleaning device cleans a surface of a sheet conveyance member which conveys a sheet in an image forming apparatus that executes image forming processing using a recording material, the surface carrying a solid substance that originates from the recording material and that adheres to the surface. The cleaning device includes a cleaning member including a contact surface configured to come in contact with the surface of the sheet conveyance member. The contact surface is an irregular surface rougher than the surface of the sheet conveyance member. At cleaning of the surface, the cleaning member makes a relative movement to the surface of the sheet conveyance member. The irregular surface is an irregular surface configured to take away the solid substance adhering to the surface of the sheet conveyance member when the cleaning member makes the relative movement.

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 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 that separates a web from a conveyance roller and brings the web into contact with the conveyance roller, and a controller. The controller includes a conveyed sheet number determination unit and a separation and contact control unit. The conveyed sheet number determination unit monitors a conveyed sheet number of both-surface image forming sheets where image forming processing is applied to both a first surface and a second surface with respect to the sheets conveyed by the conveyance roller, and determines whether or not a cumulative value of the conveyed sheet number has reached a predetermined threshold value. 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 by a pressing roller when the cumulative value of the conveyed sheet number has reached the threshold value.
