PURPOSE:To use a form without any waste by the sufficient transfer of a toner image and to eliminate the need of executing copying work, again, even if the form is doubly sent to a transfer device. CONSTITUTION:A transferring/separating charger 4 transferring the toner image on the fed form in an electrostatic transfer method, is provided. A photosensor 8 detecting the number of doubly sent forms by the quantity of light from a light source 7, transmitting the form is provided. When the photosensor 8 detects the number of the doubly sent forms, a CPU 11 executes control via a transferring/separating high voltage transformer 14, so that a transfer voltage applied to the transfer part 4a of the transferring/separating charger 4 is increased according to the number of the doubly sent forms. |
