Abstract:
In an image forming apparatus, a voltage applied to a pre-transfer charger is set to the highest voltage, and is then reduced at a position corresponding to a predetermined range from a leading edge of a recording material, to suppress a phenomenon of backward scattering of toner formed just before entering a transfer nip, when a burr formed on the leading edge of the recording material exits the transfer nip.
