Abstract

PURPOSE:To lessen manpower by performing image formation on the 2nd side for all the image carrying medias present in a housing means irrespective of the setting number by a setting means for the number of desired image forming sheet. CONSTITUTION:A both-sides copying machine is so arranged that, when there is overlapped feeding of paper during the 1st side copying, the 2nd side copying is executed until there are no more sheets of copying paper left in a relay tray even if the copying paper of the sheet number more than the preset sheet number exists in the relay tray. In this case, it turns out that the number of sheet at copying end of a lower display device displays the number more than the setting number of sheet. In this way, the image formation is made on the 2nd side for all the image carrying media present in the housing means irrespective of the setting number by input keys; therefore, even if there is overlapped feeding during the 1st side image forming and there are image carrying media which are not formed with the 1st side image, the image carrying media formed with images on both the 1st and 2nd sides is obtained surely by as much as the setting number of sheet.
