Abstract
Apparatus for cleaning residual toner from a biased transfer roll (BTR) in an electrophotographic apparatus using a metal or polymeric blade. The cleaning apparatus includes, a cleaner housing mounted adjacent to the BTR, the housing comprising a cleaner sump to which the cleaning blade is rigidly mounted and positioned in interference with the BTR such that its beam deflection provides the force required to clean the surface of the BTR. The cleaning apparatus which is used for removal of residual toner particles from the hard, smooth surface of the BTR is low cost, efficient and significantly smaller than current BTR cleaning devices.
