Abstract: A medium conveying device includes an alignment member, a skew conveying member, and a removal member. The alignment member faces one end of a medium and aligns the medium while contacting with the medium when the medium is conveyed in a first direction. The skew conveying member conveys the medium in a second direction crossing to the first direction so that the one end comes in contact with the alignment member and that includes a drive member and a driven member opposed to the drive member and driven by the drive member. The removal member has a tip end coming in contact with a face of the drive member to remove a deposit on the face. The removal member is placed along a rotation direction of the drive member so that the tip end faces downstream of the rotational direction.

Abstract: A reversing transporting device includes a transport-in path, a first transporting section provided at the transport-in path, a second transporting section provided at the transport-in path, a reversing path connected to the transport-in path, a third transporting section provided at the reversing path, a transport-out path connected to the reversing path, a fourth transporting section provided at the transport-out path, and a fifth transporting section provided at the transport-out path.

Abstract: An image forming system includes an image forming unit, a feeding unit, a side edge reversal unit, a leading edge reversal unit, and a control unit, wherein, when there is a request for image formation on a bundle of sheets including a special sheet having a special part at an edge so that the edge is not straight and there is a request for image formation on both surfaces of the special sheet, the control unit controls the feeding unit, the image forming unit, the side edge reversal unit, the image forming unit to transport the special sheet having the image of the preceding page formed thereon to the downstream side after the front and back of the sheet are reversed by the leading edge reversal unit.

Abstract: A medium conveying device includes a first guide member, a second guide member, a conveying member, and a support member. The first guide member guides one face of a medium to be conveyed and opposed to the one face when the medium is conveyed. The second guide member guides the other face of the medium and is opposed to the other face when the medium is conveyed, the second guide member being movable between a close position and an open position. The conveying member is provided in a conveying passage formed by the first guide member and the second guide member being at the close position in order to convey the medium in the conveying passage. The support member keeps the second guide member at the open position and is provided at a position outer than the second guide member in a direction that the medium is conveyed. When the second guide member is at the open position, the medium in the conveying passage is removable from the conveying passage.
