A sheet detection device includes a measurement unit for measuring a feature amount of a sheet conveyed by a conveyance unit, a pressing member movable between a first position separated from the measurement unit and a second position closer to the measurement unit than the first position, and a moving unit configured to move the pressing member, wherein the pressing member is arranged by the moving unit at the first position in a case where the sheet has not been conveyed by the conveyance unit to a measurement position of the measurement unit, wherein the moving unit is configured to move the pressing member to the second position from the first position in a case where the sheet has been conveyed by the conveyance unit to the measurement position of the measurement unit.

A recording medium conveying device includes an endless belt to convey a recording medium, a plurality of support rollers around which the belt is wound, to rotate the belt, and a cleaner in contact with the belt to clean the belt. One of the plurality of support rollers is a separation support roller, mounted on a tiltable rotary shaft, to separate the recording medium from the belt using a curvature of the separation support roller. The separation support roller includes a contact member to contact an edge of the belt when the belt laterally moves toward one side of the belt.

A transport device includes a transporting belt including an outer peripheral surface where a medium is placeable, the transporting belt being configured to transport the medium, a wiper blade including a tip portion configured to come into contact with the outer peripheral surface, and a base end portion located on an opposite side of the tip portion in an intersecting direction intersecting with the outer peripheral surface, the wiper blade being configured to wipe the outer peripheral surface, a contact portion made of resin and configured to support the base end portion by coming into contact with the base end portion, and a plurality of pressing units provided side by side in a width direction of the transporting belt, the plurality of pressing units being configured to press the base end portion via the contact portion.

A sheet processing apparatus includes a conveyance unit configured to convey a sheet in a sheet conveyance direction, a punching unit configured to punch a hole to the sheet being conveyed by the conveyance unit, a moving unit configured to move the punching unit in an intersecting direction intersecting the sheet conveyance direction, a detection unit arranged upstream of the punching unit in the sheet conveyance direction and configured to change an output value based on a position of an edge portion, in the intersecting direction, of the sheet being conveyed, a cleaning portion configured to clean the detection unit, and an interlocking portion configured to move the cleaning portion so as to clean the detection unit by interlocking with a movement of the punching unit in the intersecting direction.

An image forming apparatus is capable of correcting a lateral deviation and/or a skew of a sheet. A pair of conveying rollers convey the sheet to a transfer position of an image. An image sensor reads the sheet on an upstream side of the transfer position in a sheet conveying direction. A control device senses a foreign substance on a reading surface of the image sensor as well as calculate a lateral deviation amount and/or a skew amount of the sheet based on an output signal of the image sensor.

A sheet feeding device includes a sheet feeding roller, a sheet conveying roller, a separation roller, and a cleaning member. The sheet feeding roller is rotated to feed the sheet in a predetermined sheet feeding direction. The sheet conveying roller is disposed on a downstream side of the sheet feeding roller in the sheet feeding direction. The separation roller forms a separation nip between the sheet conveying roller and the separation roller. The cleaning member is disposed on an upstream side of the separation nip in the sheet feeding direction, and cleans a surface of the separation roller. The cleaning member is configured to be deformable to be separated from the surface of the separation roller when the sheet feeding roller does not feed the sheet and to come into contact with the surface of the separation roller by the sheet fed by the sheet feeding roller.

A transport device 3 includes a transport roller 53 that transports a medium P along a transport path TR of the medium P; a paper dust attracting roller 54 that is arranged at a position facing the transport roller 53 and that attracts paper dust clinging to the medium P; a paper dust removal section 55 that contacts the paper dust attracting roller 54; and a paper dust transport section 60 that is provided at a position adjacent to the paper dust removal section 55 and that transports the paper dust removed by the paper dust removal section 55, wherein the paper dust attracting roller 54 and the paper dust removal section 55 are configured such that contact pressure when the paper dust attracting roller 54 and the paper dust removal section 55 contact each other differs in an X-axial direction.

A control device includes a processor configured to perform, in a feeding device including a feeding unit that feeds out a feeding target loaded on a loading unit and a cleaning unit that cleans the feeding unit in a state where the feeding target is exhausted from the loading unit, notification control of issuing notification to prompt a user to take out the feeding target from the loading unit on a notification unit in a case where an addition state in which the feeding target is added to the loading unit occurs before the feeding target is fed out and exhausted from the loading unit.

The recording apparatus includes a recording unit configured to perform recording on a medium, a support unit capable of supporting the medium, a moving unit configured to move the support unit between a first position facing the recording unit and a second position separated from the recording unit, and an air flow generation unit configured to generate at least an ejection air flow in a direction from the recording unit toward a position of the support unit present at the first position in a period in which the support unit moves toward the first position or the second position.
