A paper feeding apparatus for use in a printer includes a sheet feeding path between a sheet feeding section and a developing section, a sheet ejecting path disposed such that a sheet on which an image is printed at the developing section is fed via a fixing section, an ejecting roller, and a reversing path to feed a sheet diverging from the ejecting path to the sheet feeding path again. The apparatus further includes a reversing tray disposed between the ejecting path and the reversing path to reverse the fed sheet, and a guide member rotatably mounted between the ejecting path and the reversing tray, to direct the sheet to the ejecting path or to the reversing tray. The guide member guides the reversed sheet from the reversing tray to the reversing path.
