PURPOSE:To lessen manpower by automatically shifting to the 1st mode after finishing image formation on the 2nd side when the number of sheets of image carrying media formed with images on both sides do not reach the set sheet number. CONSTITUTION:Assuming the desired copying sheet number is 20 sheets, and the number of the copying paper housed in a paper feed table is 15 sheets, the 1st side copying mode displaying and the 1st side copying mode at copying sheet number display 20-0 are started by copying start ON. At the time of 20-15, the quantity of the sheets remained in the feed table is zero and the 1st side copying mode is stopped and ended. The 2nd side copying is started by the next copying start ON signal, and when the copying sheet number coincide with the copying set sheet number, that is, when the copying sheet number displays 15-15, the 2nd side copying ends simultaneously. At this time, the 2nd side copying mode shifts to the 1st side copying mode, and the copying sheet number displays shifts from 15-15 to 20-15. Namely, the preparation for copying of insufficient 5 sheets of the ended sheet number 15 for the initial set sheet number 20 is carried out. |
