Abstract (en)
[origin: WO03036393A2] The invention relates to a method and devices for cleaning the surfaces of applicator rollers (12), photoconductor drums, transfer belts and photoconductor belts using magnetic roller systems (14, 16). The invention also relates to methods and systems for cleaning magnetic rollers (24, 44) to whose surfaces toner particles adhere. In a first embodiment, a squeegee (82) is disposed at a distance to the surface of the roller (24, 44). In another embodiment, a magnetic stator configuration with two spaced apart magnetic elements (142, 144) is used whose poles (N, N) have substantially the same active direction.
