Image Forming Apparatus Configured to Execute Duplex Printing

摘要

An image forming apparatus has an image forming device, a sheet discharge tray, a switchback mechanism configured to reverse a conveying direction of the printing sheet to re-convey the printing sheet toward the image forming device, and a casing accommodating the image forming device. The casing has a discharge opening and a switchback discharge opening through which a part of the printing sheet is projected toward the sheet discharge tray. The image forming apparatus further has a first projection-forming device configured to form a corrugation on at least one of a first printing sheet a part of which is projected toward the sheet discharge tray through the switchback discharge opening and a second printing sheet which is to be discharged onto the sheet discharge tray through the discharge opening, the corrugation having at least one deflection which projects in a direction of thickness of the printing sheet.

主权项

1. An image forming apparatus, comprising:
an image forming device configured to form images on a printing sheet; a sheet discharge tray configured to receive the printing sheet on which image formation by the image forming device has been completed; a switchback mechanism configured to reverse a conveying direction of the printing sheet to re-convey the printing sheet toward the image forming device; a casing accommodating the image forming device, the casing having:
a discharge opening through which the printing sheet is discharged from inside of the casing to outside of the casing; anda switchback discharge opening through which a part of the printing sheet is projected toward the sheet discharge tray; and a first projection-forming device configured to form a corrugation on at least one of a first, printing sheet a part of which is projected toward the sheet discharge tray through the switchback discharge opening and a second printing sheet which is to be discharged onto the sheet discharge tray through the discharge opening, the corrugation having at least one deflection which projects in a direction of thickness of the printing sheet.
