An image forming apparatus including an image reading table and comprising: a document bed installed on an upper side of the image reading table, to support a document; an image reading sensor installed under the document bed, to perform an image reading operation; a cover to cover the document bed; an automatic document feeder (ADF) to feed a document along an image reading path, past the image reading sensor such that an ADF scanning area of the document bed overlaps with a flatbed scanning area of the document bed; a document discharging plate to support a document discharged from the ADF; and a guide film to guide a document fed by the ADF along the image reading path, the guide film installed in the ADF such that, when the cover is in a closed position, the guide film establishes contact with the document bed and the document being fed is exposed to the image reading sensor through the guide film and the document bed, wherein the guide film is replaceably attached to a guide film support member of the ADF so that when the guide film is contaminated, the contaminated guide film can be readily detached from the guide film support member and replaced with a new guide film.
