Abstract
Abstract An image forming apparatus has a document table for placing a document thereon on the upper surface thereof. A scanner and a printr are provided in the apparatus. The scanner scans an image formed on the document placed on the document table. The printer forms an image based on the scanned data from the scanner. A document cover for covering the document placed on the document table is arranged on the upper portion of the apparatus. A keyboard unit is arranged on the upper surface of the document cover. An operator inputs operation data to the scanner and the printer through the keyboard unit.
