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 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 translation: 激光扫描单元包括扫描透镜，控制部分和存储部分。 控制部分控制从光源发射的光束的光量。 存储部分存储其中预先获得的表示扫描透镜的图像高度与波前像差量之间的关系的像差特性。 控制部在执行扫描时，根据像差特性，将光量设定为预定的第一光量，在波前方的第一图像高度处控制光束的光量 像差量具有第一值，并且在波前像差量具有大于第一值的第二值的第二图像高度的点处将光量设置为大于第一光量的第二光量。

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 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.
