发明名称 Multi-color image forming apparatus capable of preventing contamination of re-charger
摘要 An image forming apparatus including a photosensitive member, a first developer for developing an electrostatic latent image on the photosensitive member, a charger adapted to charge the photosensitive member bearing a first developed image formed by the first developer and having a discharge electrode member and a shield member surrounding the discharge electrode member, an exposure device for image-exposing the photosensitive member charged by the charger, a second developer for developing an electrostatic latent image formed by exposure of the exposure device, and a voltage apply device for applying voltage having the same polarity as that of the first developed image to the shield member.
