  • Publication number: 20140265106
    Abstract: An image forming apparatus includes an output unit, a pair of output rotary bodies, and a controller. A sheet having an image formed thereon is discharged to the output unit. When plural sheets are sequentially discharged to the output unit, the controller controls overlapping output operation to, with a trailing end portion of a preceding sheet of the plural sheets being held by the pair of output rotary bodies, feed a subsequent sheet of the sheets to between the pair of output rotary bodies to overlap a leading end portion of the subsequent sheet with the trailing end portion of the preceding sheet. With the leading end portion of the subsequent sheet overlapped with the trailing end portion of the preceding sheet, the controller controls the pair of output rotary bodies to rotate to discharge the preceding sheet to the output unit.

  • Publication number: 20140009531
    Abstract: An image forming apparatus includes an apparatus body, a recording head, a cap member, and release valves. The head has a nozzle face with nozzles to eject liquid droplets. The head is placed in the apparatus body so as to eject the droplets obliquely downward in any of the vertical or horizontal arrangement of the apparatus body. The cap member caps the nozzle face and has openings at opposed ends in a longitudinal direction of the cap member to communicate an inside of the cap member with an outside of the cap member. The valves open and close the openings relative to an atmosphere. One of the valves placed higher than another one of the valves in accordance with the vertical or horizontal arrangement is configured to open the inside of the cap member to the atmosphere through one of the openings placed higher than another one of the openings.
