Abstract
A device for preventing contamination of a print sheet and the reduction in the effectiveness of a scorotron type charger by free toner and paper particles. The device includes a paper dust eliminator extending the length of a photosensitive member and a wiping mechanism at each end of the photosensitive member for removing free toner that has accumulated there. Further, a partition that separates the developing section from the charger can be provided to further reduce free toner from attaching to the charger.
