  • Method and apparatus for cleaning remnant toner and carrier particles
    Patent number: 5937254
    Abstract: An electrostatographic reproduction apparatus and method for cleaning remnant toner and carrier particles. An intermediate transfer member (ITM) is in transfer relation to a primary image-forming member to transfer the toner image from the primary image-forming member to the ITM. The ITM then transfers the image to a receiver sheet . A fiber cleaning brush includes plural individual conductive brush fibers in engagement with the ITM to remove residual toner and carrier particles from the ITM. A detoning member 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 member includes magnets for attracting remnant carrier to the detoning roller and for attracting a skive blade of magnetic material into engagement with the detoning roller.
