CLEANING DEVICE AND IMAGE FORMING APPARATUS

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.

CLEANING DEVICE AND IMAGE FORMING APPARATUS PROVIDED WITH THE CLEANING DEVICE

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.

CLEANING DEVICE AND IMAGE FORMING APPARATUS INCLUDING THE SAME

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.

A dust removal device for continuous paper improves operability and usability for a user. The continuous paper is continuously supplied in a rightward direction, then through guide rollers, the direction of the continuous paper is reversed leftward. A downward front surface of the continuous paper is cleaned with a first dust removal device. Further, a direction of the continuous paper is reversed with a guide roller rightward. A downward back surface of the continuous paper is cleaned with a second dust removal device, and is guided to the downstream side. The two dust removal devices are provided in a vertical positional relationship in space. Dust removed with a dust removing member falls to a dust receiving member and is stored in the dust receiving member. It is possible to easily dispose the dust by pulling out the dust removal device from a cleaning position to an outside detachment position.
