Image forming apparatus utilizing intermediate transfer member
 An image forming apparatus having a photosensitive drum and a transfer drum including a transfer member carrying sheet substantially contacting the photosensitive drum. In order to enable a toner image formed on the photosensitive drum to be efficiently transferred to a transfer member, the apparatus has a pressing sheet for outwardly pressing the transfer member carrying sheet from the interior of the transfer drum and a conductive member provided on the side of the pressing sheet adjacent the transfer member carrying sheet. The conductive member serves to realize a uniform distribution of surface potential on the pressing sheet and to maintain the surface potential constant, so that the intensity of the electric field applied to the corona discharge is made constant at a low level so that a stable transfer corona is applied to the transfer member carrying sheet, thus ensuring good quality of the transferred image.
