Abstract
An image forming apparatus includes an image bearing member for bearing an electrostatic image. A developing device develops the electrostatic image on the image bearing member by toners charged with a predetermined polarity. A transfer device transfers a toner image on the image bearing member to a transferring material. An electrifying device inject-charges the image bearing member having transfer residual toners. An electrical conductive member provided and spaced apart from the image bearing member in a moving direction of the image bearing member downstream farther than the transfer means and upstream farther than the electrifying device. An electrical field forming device for forming an alternative electrical field between the electrical conductive member and the image bearing member.
