摘要： An image forming apparatus includes an image forming portion that superposes images on an intermediate transfer member by rotations of the intermediate transfer member to form a color image on the intermediate transfer member, a transfer portion that transfers the image formed on the intermediate transfer member in the image forming portion to a sheet, a fixing portion that fixes the image onto the sheet, and a switchback portion that switches back the sheet so as to return the sheet to the transfer portion for forming the image on a second face of the sheet, after the image has been formed on a first face of the sheet. The sheet is returned through a return path at a return speed equal to or lower than a delivery speed of the sheet in the transfer portion, when the image for the second face of the sheet is the color image.

摘要： An automatic document feeder includes first and second registration rollers for abutting the leading end of an original conveyed along a conveying path against their contact positions. The first registration roller is included in a plurality of reversing rollers arranged apart from each other along an axis of a supporting shaft of each of the reversing rollers. The reversing roller turn over the original along a reversing path that bypasses a part of the conveying path. There is provided a reversal guiding member arranged so as to cover a region between the adjacent reversing rollers. The reversal guiding member has guide surfaces curved along the peripheral surfaces of the reversing rollers as viewed along the axis of the supporting shaft. The reversal of the original is guided along the reversing path by the guide surfaces.

摘要： A recycle document feeder according to the present invention includes a pair of document width regulating guides (9a, 9b) for guiding opposite edges of document originals (D) fed back onto a document placing plate (8) for alignment thereof with respect to the width thereof. With this construction, if the document width regulating guides (9a, 9b) each had a small length (A) as measured along a document transportation direction, the document originals (D) fed back onto the document placing plate (8) could not properly be aligned by the document width regulating guides (9a, 9b) thereby to be randomly stacked on the skew with respect to the document transportation direction. In view of this, the document width regulating guides (9a, 9b) are constructed so as to guide the document originals fed back onto the document placing plate (8) from a document discharge portion (30) over a distance equivalent to or greater than 60% of the length of a smallest document original (as measured along the transportation direction) which is to be possibly transported by the recycle document feeder.

摘要： In an automatic document feeder, an original tray has an original platen on its upper surface. Originals put on the original platen are fed along a conveying path by conveying rollers and conveyance auxiliary rollers. The originals fed are separated one at a time by separating belts and separating rollers which are arranged above and below a conveying path. When a conveyance guide plate constituting a part of the original platen is removed upward, the separating rollers, the conveying rollers, and the conveyance auxiliary rollers and a portion for supporting the rollers are exposed upward, so that maintenance such as replacement of components such as the separating rollers, the conveying rollers and the conveyance auxiliary rollers can be performed.
