ABSTRACT:
For removing toner from a photosensitive drum roll for electrophotography, a blade contacts the surface of the drum roll at a location where said surface is moving upwardly, to scrape residual toner therefrom. A resilient transfer roll, spaced below the blade, carries away toner that falls from the drum roll. The transfer roll is directly rotatably driven by the drum roll. One of the rolls has enlarged diameter end portions for driving contact between the rolls at zones outside the image area of the drum roll. The resilient transfer roll is urged toward the drum roll under a biasing force that radially compresses its end portions to maintain it either in merely line contact with the image area of the drum roll or spaced from that area by a distance less than the diameter of toner particles.
