Abstract: An image reading device includes a main body including a light transmissive plate on a top surface of the main body, a document placing plate on the top surface of the main body adjacent to the light transmissive plate in a first direction to place a document, and an image reader movable under the light transmissive plate and the document placing plate in the first direction to read image on the document, and a document conveyor including a document setting unit to set the document, a document conveyor movable between an open position and a closed position, and an image pattern portion at a bottom surface of the document conveyor, the image pattern portion having an image pattern to be read by the image reader at a position under the light transmissive plate.

Abstract: An image forming apparatus including an image carrier for forming a toner image thereon. A conveyor conveys a synthetic resin sheet. An image transferring device transfers the toner image from the image carrier to the synthetic resin sheet being conveyed by the conveyor. A fixing device is located downstream of the image carrier in a direction of sheet conveyance for fixing the toner image transferred to the synthetic resin sheet. The fixing device includes a heat roller capable of contacting the synthetic resin sheet. The heat roller is freely rotatable and caused to rotate by the synthetic resin sheet being conveyed by the conveyor when the sheet contacts the heat roller.

Abstract: A printer or similar electrophotographic image forming apparatus for forming an image on an optical disk or similar synthetic resin sheet is disclosed. The apparatus of the present invention guarantees a sufficient period of time for fixation to thereby obviate defective fixation while producing as great a number of prints as possible. At the same time, the apparatus of the present invention saves energy and space and accurately matches the peripheral speed of a heat roller and the conveying speed of the synthetic resin sheet.
