Abstract: A cleaning device includes a cleaning unit and a unit moving mechanism. The cleaning unit brings a web into contact with a conveyance member rotating around an axis and removes foreign matter adhered to the conveyance member. The unit moving mechanism displaces the cleaning unit to a cleaning position where the web is brought into contact with the conveyance member and to a separation position where the web is separated away from the conveyance member. When the unit moving mechanism displaces the cleaning unit from the cleaning position to the separation position, the cleaning unit is displaced in a counter direction opposite to a rotational direction of the conveyance member on a contact face between the conveyance member and the web.

Abstract: A cleaning device includes a controller configured to control cleaning of a conveyance roller by a web. 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 is configured to control a 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 in a state where the web is pressed to the conveyance roller. The take-up control unit is configured to allow the take-up roller to perform a take-up operation of taking up the web by rotatably driving the take-up roller plural times at a predetermined time interval within a cleaning time set in advance in a state where the conveyance roller is being rotated.

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.

IPC: G03G21/00
Abstract: A cleaning device includes a cleaning unit, a movement mechanism, and a positioning portion. The cleaning unit includes a cleaning part that has a contact surface extending along an axial direction of a conveyance roller and cleans the conveyance roller, 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. 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 removed from the apparatus body. The positioning portion restricts a relative position between the cleaning part and the conveyance roller by being brought into contact with the cleaning unit.

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.

Abstract: A laser scanning unit includes a scanning lens, a control portion, and a storage portion. The control portion controls a light amount of a light beam emitted from a light source. The storage portion stores therein aberration characteristics representing a relationship between image heights of the scanning lens and a wavefront aberration amount, which have been obtained in advance. The control portion, when the scanning is performed, controls the light amount of the light beam in accordance with the aberration characteristics, such that the light amount is set to a predetermined first light amount, at a point of a first image height where the wavefront aberration amount has a first value, and the light amount is set to a second light amount larger than the first light amount, at a point of a second image height where the wavefront aberration amount has a second value larger than the first value.

Abstract: A control unit determines nozzles corresponding to the image to be printed and causes a recording head to eject ink from the nozzles. A correction processing unit performs a correction process corresponding to each of ink ejection malfunction positions in the image. The correction processing unit (a) prints a test pattern using the recording head, (b) determines the ink ejection malfunction positions on the basis of a scanned image of the test pattern, (c) determines a droplet hit position deviation amount of the ink at each of the ink ejection malfunction positions, and (d) determines a print sheet type of the print sheet, performs comparison between the droplet hit position deviation amount and a threshold value set for the print sheet type, and determines whether the correction process should be performed to the ink ejection malfunction position or not on the basis of a result of the comparison.
