Image Forming Apparatus

摘要

An image forming apparatus with a duplex printing function may include a closeable and openable portion. In one example, the portion may correspond to a cover of the image forming apparatus. The cover may include guiding portions configured to define a return path for duplex printing. In another example, the portion may correspond to a document reading unit including an outer casing. A portion of the outer casing may be configured to guide a recording sheet that is conveyed out of a housing of the image forming apparatus by a switchback roller. In one example, the switchback roller may convey a recording sheet to a position above an upper surface of the outer casing.
