Abstract: A conveying path switching structure includes a cover unit and a conveying path switch unit. The cover unit is attached to an image forming apparatus main body so as to be movable between a close state and an open state in which a fixing unit is exposed. The conveying path switch unit is rotatably attached to the cover unit and that switches a conveying path of a record medium between a discharge conveying path and a double-side conveying path. The discharge conveying path is a path where the record medium is conveyed from a discharge part of the fixing unit to a discharge unit that discharges the record medium to outside of the image forming apparatus main body in a close state. The double-side conveying path is a path where the record medium is conveyed again to an image forming unit.
