Abstract
An image forming apparatus includes an image bearing member for bearing a developer image; an image forming apparatus for forming the developer image borne on the image bearing member; a transferring apparatus for electrostatically transferring the developer image on the image bearing member to a transferring material in a transferring area; and a guiding member for guiding the transferring material into the transferring area. The guiding member includes an insulating member disposed on a transferring material guide surface and a conductive member disposed on a surface opposite to the transferring material guide surface. A power source capable of applying a voltage having a predetermined polarity is electrically connected to the conductive member. A projection is provided on the surface of the insulating member.
