ABSTRACT:
An image transfer system includes an image bearing member made of a photoconductive layer and an electrically conductive backing layer, a current detector connected between the backing layer and ground, a transfer corona unit for applying corona ions to a back side of a transfer sheet brought into contact with the exposed surface of the photoconductive layer on which a toner image is carried, a power supply for applying power to the corona unit, and a controller for controlling the power supply in response to a current level detected by the current detector. This system maintains the image transfer efficiency substantially at a constant level irrespective of the condition of transfer sheet used, and in particular to the water content of the sheet.
