The image forming apparatus has charging device, developing device, transfer-charging device, and control device for controlling a charging bias applied to the charging device. In the image forming apparatus, the transferring material to which the developer image is transferred is separated from the photosensitive body by the transfer-charging device, and the control device reduces the charging bias such that a surface potential of the photosensitive body in the case where the developer image is formed on the transferring material having low rigidity is lower than the surface potential of the photosensitive body in the case where the developer image is formed on the transferring material having high rigidity.
