Abstract: An inclined flange roller is located outward of an end portion of a tension roller in the belt width direction. The inclined flange roller includes a flange surface capable of being in contact with the edge portion of a belt in a region in which the belt is wound around the tension roller and a roller surface capable of being in contact with an inner peripheral surface of the belt between the flange surface and an end portion of the tension roller in the belt width direction.

Abstract: An image forming apparatus includes a first conveying path guiding a sheet such that the sheet passes through the image forming portion, a second conveying path guiding the sheet on which the image is formed by the image forming portion to the first conveying path. A document is fed to the second conveying path and the image forming apparatus includes a first drive transmission portion transmitting a drive force to the image forming portion and a second drive transmission portion transmitting the drive force to a document feeding portion, a conveyance portion and a document discharge portion.

Abstract: An image forming apparatus includes a sheet feed portion configured to feed a sheet, an image forming portion configured to form an image on the sheet, a first conveying path configured to guide the sheet fed from the sheet feed portion such that the sheet passes through the image forming portion, a second conveying path configured to guide the sheet on which the image has been formed on one surface thereof by the image forming portion to the first conveying path again, a document feed portion configured to feed a document to the second conveying path, an image reading portion configured to read an image of the document fed by the document feed portion, and a control portion configured to control the sheet feed portion and the document feed portion such that the document and the sheet are conveyed on the second conveying path in a sequence in which the document and the sheet are mixed in a case where an operation of forming images respectively on both surfaces of a plurality of sheets overlaps with an operati

Abstract: An image forming apparatus includes a first conveying path which connects between a sheet feed portion and a sheet discharging portion, and on which a image forming portion is arranged. The image forming apparatus further includes a second conveying path configured to guide the sheet on which the image has been formed on one surface thereof by the image forming portion to the first conveying path again, a document conveying path, and a reading portion. The document conveying path includes a document feeding path, a document discharging path, and a common conveying path which serves as at least a part of the second conveying path, and guides the document from a document feed portion to a document discharging portion through the document feeding path, the common conveying path and the document discharging path without causing the document to pass through the image forming position. The reading portion reads a first face and a second face of the document which is fed from the document feed portion.

Abstract: An image forming apparatus includes a document separation and feed portion separating and feeding a document, a document discharge roller pair discharging the document, and a sheet discharge roller pair discharging a sheet. The document separation and feed portion or the document discharge roller pair is disposed so as to overlap with the sheet discharge roller pair in a vertical direction.

Abstract: A rotating member provided on an end of a stretching member is rotatable around a rotating axis inclined with respect to the shaft of the stretching member. In order that, when a belt end winds around the rotating member, the belt end winds around an outer side of an entry position where the belt end enters the rotating member, an outer circumferential surface of the rotating member in an area in contact with an inner circumferential surface of the belt is inclined with respect to a belt contact surface.

Abstract: A reading apparatus including: a first conveyance path in which a sheet is conveyed; a second conveyance path different from the first conveyance path, the second conveyance path allowing the sheet switched back after having passed through the first conveyance path to be conveyed therein; a reading unit configured to read the sheet, the reading unit being movable to a first position where a first surface of the sheet in the first conveyance path is read, a second position where a second surface as a back surface of the first surface of the sheet in the second conveyance path is read, and a third position different from the first position and the second position; and a reference portion that the reading unit reads for correcting information read by the reading unit, the reference portion being read by the reading unit moved to the third position.
