摘要： An image forming apparatus includes a sheet container accommodating a recording medium therein, a sheet separating feeder including a sheet feeding body and a sheet separating body, an image forming part, and a bend applier. The sheet feeding body feeds the recording medium along with a surface movement thereof while the recording medium contacting the surface thereof. The sheet separating body forms a sheet separation nip region with the sheet feeding body and sandwiches the recording medium in the sheet separation nip region. The sheet separating feeder separates and feeds the recording medium contacting the sheet feeding body. The image forming part forms an image on the recording medium. The bend applier having a leading end of an elastic material contacts and bends the recording medium before the sheet separation nip region and generates a wrinkle extending on the recording medium in a sheet conveying direction.

摘要： An image forming apparatus includes an image forming unit, a paper loading base on which manual-feed paper is loaded, a manual-feed paper conveying unit, and a dustproof cover which covers the paper loading base being in the overhang state. The paper loading base has a lower end rotatably supported on one outer surface portion of the device main body, and is opened from an upper end thereof and disposed at a predetermined oblique angle or in a horizontal overhang state such that an overhang side becomes an upper side in an oblique direction. The manual-feed paper conveying unit is conveys the manual-feed paper on the paper loading base onto a paper conveyance path one by one. The dustproof cover includes a base which engages with the paper loading base, and an opening-and-closing cover which is rotatably connected to the base and is opened upwardly on the overhang side.

摘要： A sheet processing apparatus including a sheet feeder, a sheet processing device, a sheet ejection device, a purge unit, a multifeed sensor, a sheet sensor, and circuitry. The circuitry stops an operation of the sheet processing apparatus when the multifeed sensor has not detected multifeed of the sheet and the sheet sensor does not detect a trailing end of the sheet after a first set time from detection of a leading end of the sheet, stop the operation when the multifeed sensor has detected the multifeed and the sheet sensor does not detect the trailing end of the sheet after a second set time from the detection, and conveys the sheet toward the purge unit without stopping the operation when the multifeed sensor has detected the multifeed and the sheet sensor detects the trailing end of the sheet before the second set time elapses from the detection.

摘要： A sheet processing apparatus including a sheet feeder, a sheet processing device, a sheet ejection device, a purge unit, a multifeed sensor, and circuitry. The sheet feeder feeds a sheet toward a sheet conveyance passage. The sheet processing device performs a predetermined operation on the sheet. The sheet ejection device stacks the sheet when the predetermined operation has been performed. The purge unit stacks the sheet when the predetermined operation has not been performed. The multifeed sensor detects whether sheets are multifed and a number of multifed sheets. The circuitry counts a number of sheets, determines that the sheets stacked in the purge unit is full when a number of counted sheets reaches a predetermined number of sheets, and conveys the multifed sheets toward the purge unit and adds the number of counted sheets according to the number of multifed sheets, in response to detection of the multifed sheets.
