Abstract

PURPOSE:To satisfactorily execute transfer and separation with regard to all modes by changing a control current of a transfer pole and a separation pole in accordance with the time of a high speed and low speed and the tie of the reverse side and the surface. CONSTITUTION:A photosensitive drum 11 rotates at a peripheral speed of two stages or three stages by selecting the magnification of variable power. To a transfer pole 14 which is shielded by a shielding member 21, a DC voltage of plus corresponding to a line speed of transfer paper is applied through a high voltage transformer which is brought to constant-current control. Also, to separation wires 15a, 15b of a separation pole 15, an AC voltage on which a DC bias brought to constant-current control is superposed is applied in accordance with line speed. Moreover, at the time of reverse side copying, a DC bias voltage of the separation pole 15 is made different from that voltage at the time of surface side copying. In such a way, in case of both one face and double face copy, a transfer and a separation can always be executed satisfactorily.
