Abstract
An image forming apparatus including a transfer discharger. A sheet material after transfer is detached from a photosensitive drum by virtue of its stiffness and its own weight. The sheet material detached from the drum is guided by a guiding member. The guiding member is made of insulating material and provided with a plurality of ribs. A charge removing member is disposed on a downstream side of the guiding member. Charge removing action occurs over spaces between the ribs and charges on a rear surface of the sheet material are removed as the sheet material is being guided by the ribs. The guiding member may be formed of antistatic material in at least a part of it which comes into contact with the sheet material. Further, the guiding member may include assisting guide portions in at least some of the spaces between the ribs for guiding a receiving substrate such as a sheet material, an envelope, or the like to upper portions of the ribs.
