PURPOSE:To be enable setting up the magnification of a high using frequency as a storage magnification by providing a storage updating means to update the content of a magnification storage means at every image forming operation by an image forming means. CONSTITUTION:A key board 42 includes a printing key 44 to instruct the start of a copying operation, an up-key 45 and down-key 46 to move increase/decrease the set copying magnification and an unmagnification key 47 to set the copying magnification at an unmagnification (100%). Whenever the copying operation is performed by depressing the printing key 44, a magnification storage subroutine is executed. Accordingly whenever the copying operation is completed, the information of the storage magnification is automatically updated. Consequently, without specially necessitating the input of the magnification in the high using frequency and even in the case that the magnification in the high using frequency is frequently changed, the magnification in the high using frequency can be used as the storage magnification. |
