Abstract
A document is conveyed by switching the direction in which the document is conveyed to a forward direction or a reverse direction by a document conveying section, thereby to make a plurality of copies from the same document. An image forming operation with illuminating and scanning by a light source is performed when the document is conveyed in the forward direction. A copy image is formed on rolled-paper suitably cut by a cutter. In a case where a plurality of copies are made, when the document is conveyed in the forward direction so as to make the first copy, the time elapsed from the start of the copying operation until the synchro sensor senses a rear end of the document is measured. The time measured is stored in a memory. The timing at which the rolled-paper is cut in operations of making the second and subsequent copies is set on the basis of the time stored in the memory. This construction makes it possible to make the lengths of copy paper sheets obtained by cutting the rolled-paper equal to each other when a plurality of copies are made.
