A sheet conveyance apparatus includes a conveyance roller, an abutment member including an abutment surface against which a side edge, in a width direction, of the sheet abuts, and configured to correct a skew of the sheet, an obliquely conveying roller configured to convey the sheet such as the side edge of the sheet is conveyed toward the abutment surface, a sheet side edge detection portion configured to detect a position of the side edge of the sheet, and a control unit configured to control that a conveyance force, in the width direction, by the obliquely conveying roller in response to a detection result of the sheet side edge detection portion becomes smaller than that in an abutment movement.

A sheet conveying device includes a first roller, a second roller, and a controller. The first roller is configured to rotate in a forward direction for sheet conveyance along a sheet conveying direction. The second roller is disposed downstream with respect to the first roller in the sheet conveying direction and configured to rotate in a forward direction along the sheet conveying direction and in a reverse direction. The controller is configured to control the second roller to rotate in the reverse direction at a timing when a leading end of a sheet that is nipped and conveyed by the first roller reaches a nip of the second roller.

A sheet feeding device includes a sheet loader, a first conveyor, a second conveyor, and a guide. The sheet loader is configured to load a sheet bundle including a sheet with a flap. The first conveyor is configured to convey the sheet with the flap loaded on the sheet loader. The second conveyor is disposed adjacent to the first conveyor. The guide is disposed below the flap of the sheet to be conveyed, between the second conveyor and the sheet loader in a sheet conveying direction of the sheet, and is configured to guide the sheet.

A sensor unit includes a first housing constituting a first conveying face of a sheet conveying passage, a second housing constituting a second conveying face arranged opposite the first conveying face with a predetermined gap, an edge detection sensor detecting a side edge along the sheet conveying direction, and a gap adjuster supporting the first housing movably in a direction in which the size of the gap increases. When, with the first housing arranged at the first position, a sheet with a thickness greater than a reference value passes through the sheet conveying passage, the first housing moves in the direction in which the size of the gap increases as the sheet enters the sheet conveying passage, to allow the passage of the sheet.

A sheet conveying apparatus includes a sheet conveyance section, a roller pair unit, first and second guides, and a movable guide including an upstream portion extending upstream in the sheet conveying direction with respect to the nip portion and a downstream portion extending downstream in the sheet conveying direction with respect to the nip portion. The roller pair unit nips the sheet, warps the sheet in a case where a leading end of the sheet conveyed by the sheet conveyance section comes into contact with the roller pair unit, and conveys the sheet. The first guide opposes a first side of the sheet and guides the sheet. The second guide opposes a second side of the sheet. The movable guide opposes the first side of the sheet and moves in such a manner that the downstream portion of the movable guide moves closer to or away from the second guide.
