Image forming apparatus having transfer electrode

摘要

The present invention provides an image forming apparatus having a shiftable image bearing member; an image forming device for forming an image on the image bearing member; and a transfer device for transferring the image formed on the image bearing member onto a transfer sheet at a transfer station, the transfer device urging the transfer sheet against the image bearing member and having a transfer electrode to which a voltage is applied; and wherein a resistance value between a surface of the transfer electrode facing the image bearing member and a portion of the transfer electrode at which the voltage is applied is greater at an upstream side of a shifting direction of the image bearing member than at a downstream side thereof, on the surface of the transfer electrode, whereby an image can be obtained without any transfer void.
