Abstract
An image forming apparatus having a document transporting mechanism which transports documents one by one from a document feed tray, to the exposure location on a platen and which prefeeds the next document to a position before the platen, and a control mechanism which in response to an instruction of stopping the image form operation controls the operation of the document transporting mechanism so as to transport a document prefed to the position before the platen, in a predetermined direction. When a trouble occurs in the main body of the image forming apparatus during the image forming operation and the stop instruction is issued, a document on the platen is immediately transported to a document discharge tray, and also a document which has been prefed to the position before the platen is transported to a predetermined position (onto the platen, the document discharge tray or the document feed tray). The prefed document is not left stand in a loop state for a long period of time, thereby preventing a document from having a tendency to curl and a document jam from occurring.
