Abstract
An image forming apparatus such as a copying apparatus and a laser beam printer, is capable of forming a superimposed image or duplex image on one sheet. The sheet which has been once subjected to the image forming operation and which is going to be subjected to another image forming operation is reintroduced into the image forming station selectively through a flow-through sheet passage or through an intermediate tray on which the transfer sheets are once stacked. A displaceable flapper is provided to direct the sheet selectively to the flow-through passage or to the intermediate tray.
