Problems solved by technology

However, since the protrusion protrudes in the radial direction from the outer peripheral surface of the lower roller forming the nip, when the sheet passes through the nip of the discharge roller, the protrusion damages the sheet, and also causes traces of the protrusion to remain on the formed surface. Disadvantages of images on sheets

Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a side sectional view showing the internal structure of the image forming apparatus 100 equipped with the sheet ejection device 30 of the present invention. An image forming unit P is arranged in the image forming apparatus (for example, a monochrome printer) 100, and a monochrome image is formed through various processes of charging, exposure, development, and transfer. The image forming portion P is along the rotation direction of the photosensitive drum 5 ( figure 1 A charging unit 4, an exposure unit (laser scanning unit, etc.) 7, a developing unit 8, a transfer roller 14, a cleaning device 19, and a charge removing device (not shown) are arranged.

[0019] During the image forming operation, the photoreceptor drum 5 rotating in the clockwise direction is uniformly charged by the charging unit 4, and an electrostatic latent image is formed on the photorecep...

Abstract

The invention provides a sheet discharging device and an image forming apparatus therewith. The sheet discharging device has a discharge port, a discharge tray, a discharge roller including first and second rollers, a flick-out pulley, a sheet pressing member, and a pressing rib. The flick-out pulley is formed coaxially with the rotary shaft of the first roller at an interval from an end of the first roller, and has a circumferential edge and a plurality of projections protruding from it. The sheet pressing member is supported on a pivot axis provided on the downstream side of the discharge roller with respect to the sheet discharge direction to be swingable in the sheet discharge direction. A pressing rib is arranged at a position overlapping the flick-out pulley in the direction along the pivot axis as seen from the sheet discharge direction.

Description

Technical field [0001] The present invention relates to a sheet discharging device for discharging sheet-like recording media such as paper, and an image forming apparatus equipped with the sheet discharging device. The sheet discharging device is used in copiers, printers, facsimiles, and digital composites having these functions Machine waiting. Background technique [0002] The image forming apparatus is provided with a discharge roller for discharging a sheet (paper) on which an image has been formed by the image forming section. The sheet conveyed from the upstream side of the discharge roller is sent out onto the discharge tray by the discharge roller. When the sheet is sent out to the output tray by the eject roller, there may be a disadvantage that the rear end of the sheet remains on the roller below the eject roller. [0003] In order to solve this disadvantage, there is a roller provided with a protrusion on the lower side of the eject roller, and the rear end of the s...
