PURPOSE:To obtain an image forming device where the images of the front and back of an original are arranged and copied on one sheet by arbitrarily changing the copying timing of a multiple copying machine. CONSTITUTION:The original is placed on an original placing means, and an image is formed on the sheet by an image forming means. The sheet is kept on a carrying path where multi-copying is carried out, and the original is inverted by an inverting means 3. Then, the sheet is refed from the carrying path and the image of the rear of the original is superimposed and copied. At this time, an instructing means instructs a control means 86 to change the timing of an image-formation, and the images of the front and back surfaces of the original are arranged and copied on one sheet. Thus, the images of the front and back surfaces of a both-side original are automatically copied on the front and the rear half parts of one sheet. |
