ABSTRACT:
An electrostatographic reproduction apparatus and method for cleaning remnant toner and carrier particles. A fiber cleaning brush includes plural individual conductive brush fibers in engagement with a toner bearing member to remove residual toner and magnetic carrier particles from the member. A detoning roller includes an electrically conductive surface that contacts the brush fibers and is electrically biased to electrostatically remove toner particles from the fiber brush. The detoning roller includes one or more permanent magnets for attracting remnant carrier to the detoning roller. A skive blade of non-magnetic material engages the detoning roller. In some embodiments, the permanent magnet is stationary and provides substantially no magnetic field where the skive blade engages the detoning roller to avoid congregation of magnetic carrier particles adjacent the edge of the blade. In another embodiment, the magnet rotates to cause carrier particles to move along the blade. In all embodiments, most of the carrier particles never reaches the blade to reduce the wear on the blade edge.
