Image forming apparatus for making recovery and restoration of toners by electrical conductive member

摘要

An image forming apparatus comprises an image bearing member for bearing an electrostatic image; a developing means for developing the electrostatic image on said image bearing member by toners charged with a predetermined polarity; a transfer means for transferring a toner image on said image bearing member to a transferring material; an electrifying means for inject-charging the image bearing member having transfer residual toners; an electrical conductive member provided and spaced apart from said image bearing member in a moving direction of the image bearing member downstream further than said transfer means and upstream further than said electrifying means; and an electrical field forming means for forming an alternative electrical field between said electrical conductive member and said image bearing member.
