PURPOSE:To prevent the residual potential of an image carrier after the image transfer from rising. CONSTITUTION:The image forming device is constituted that in addition to the pre-charge exposure means PCL, a pretransfer exposing means PTL is placed in a position on the upstream side in the rotating direction of the photoreceptor drum of the transfer unit, made in a state of lighting in synchronism with the rotation of the PCL photreceptor drum, and the PTL is turned on so as to expose the photoreceptor surface for avoiding the image area on the photoreceptor or the transferring time of the image, by this way the residual voltage of the photoreceptor after transferring is prevented from rising without damaging the transferring image. |
