Abstract

The present invention provides an image forming apparatus having, an image bearing member; an image forming device for forming an image on the image bearing member; a transfer sheet bearing device for bearing and conveying a transfer sheet, to which a first voltage is applied for transferring the image formed on the image bearing member onto the transfer sheet born by the transfer sheet bearing device; and a discharging device for causing the discharge in the transfer sheet when the transfer sheet is separated from the transfer sheet bearing device, to which a second voltage having the same polarity as that of the first voltage and having a value equal to 80%-120% of the first voltage is applied.
