装置。[Claims for Utility Model Registration] A toner image formed on a photoconductor is transferred directly to a dielectric transfer belt that is conveyed straight in contact with the photoconductor, or to a transfer paper that is carried and conveyed by the transfer belt, In a transfer device of an image forming apparatus that performs transfer by a transfer corona discharge means, the transfer charge of the transfer corona discharge means reaches the transfer belt inlet side of the transfer corona discharge means near a position where the photoreceptor and the transfer belt are in close contact. The transfer charge regulating member is provided so that the tip of the transfer charge regulating member is in contact with the back surface of the transfer belt at the position where it contacts the photoreceptor, or with a pressing force that does not cause the transfer belt to bend. transfer device.
