ABSTRACT:
An image forming apparatus is provided to suppress a separation discharge effectively at a sheet separation time thereby to effectively prevent the disturbance of a toner image on a sheet, as might otherwise be caused due to the separation discharge. The image forming apparatus includes an image carrier for carrying a toner image, a conveyance/transfer unit including at least a sheet conveyor for holding and conveying, for transferring the toner image on the image carrier electrostatically to the sheet, and a sheet separation aiding unit for aiding the action of separating the sheet from the sheet conveyor. The sheet separation aiding unit includes a discharge electrode member arranged downstream of a sheet separating portion of the sheet conveyor and at a position capable of discharging between itself and the sheet conveyor, and a bias applying unit for discharging between the discharge electrode member and the sheet conveyor. The discharged ions, as generated from the discharge electrode member, are fed to the vicinity of the sheet separating portion of the sheet conveyor.
