PURPOSE:To facilitate copying operation by allowing an image formation position on a transfer material to be selected for the mount position of an original, changing the image formation position every time transfer materials circulate plural times, and varying copying magnification properly unless image area coincides with transfer material area. CONSTITUTION:When the image of a single original is copied on a single transfer material, the transfer material passed through a copying process 9 is guided to a fixing device 27 by a conveyor belt 10 and a developer image is fixed. Then, the transfer material is discharged onto a paper discharge tray 15. In image composing formation mode, the transfer material passed through the copying process 9 is guided to a fixing device 27 and then guided to a paper feed part 9 again through a circulation path 12 to stop at the position of a timing roller 14. A transfer material fed out of a form cassette 3 and the transfer material reaching the paper feeding part 4 through the circulation path 12 reach the timing roller 14 prior to the rotation of a photosensitive drum 2 and the timing roller 14 rotates in synchronism with the rotation of the photosensitive drum 2 to guide the transfer materials to the copying process 9. |
