  • Patent number: 8041281
    Abstract: A cleaning device removes residual toner particles from a cleaning target, such as a photoconductor, which has a moving surface. The cleaning device includes a cleaning brush, a power circuit, and a cleaning member. The cleaning brush includes a brush rotation shaft, and the power circuit applies a first voltage of a first polarity to the brush rotation shaft. The cleaning member applies a second voltage of the first polarity to the cleaning brush. If the first polarity is negative, the cleaning member electrostatically removes toner particles having a positive polarity from the cleaning target. Then, the cleaning brush is triboelectrically charged to a second polarity, which is opposite to the first polarity, by contacting the cleaning target. Accordingly, the cleaning brush also removes residual toner particles having a negative polarity. Thus, the cleaning device removes both positively and negatively charged toner particles to clean the cleaning target.
