ABSTRACT:
In electrographic apparatus a latent image on a flexible photoconductor is developed with toner particles at a development station and subsequently transferred to a receiver sheet, such as a copy sheet, and then fused to the sheet. Sometimes unwanted particles are on the photoconductor, including the area where an image is to be developed on the photoconductor. These particles are removed by a magnetic brush system located closely adjacent the surface of the photoconductor prior to the charging station. By means of a pair of tapered skis the cleaning pressure across the photoconductor is maintained at a uniform pressure during cleaning of the photoconductor so that the photoconductor is uniformly cleaned.
