ABSTRACT:
An electrophotographic copying machine capable of inserting an inter-sheet in a copy of a document. A width-detector is provided to detect the width of an inter-sheet contained in an inter-sheet tray. A judging circuit determines if the detected width of the inter-sheet is within an allowable width range. If the detected width is not within the allowable width range, the inter-sheet is inhibited from being fed and reminder information is displayed. If the inter-sheet is required to be blank with no image of the original recorded thereon, an automatic document feeder is controlled so as to stop feeding the original sheet while the inter-sheet is conveyed to be placed at the insert-page. The adjustment of copy image density, including scanning of the original sheet, is also stopped.
