摘要： 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.
摘要翻译：清洁装置从具有移动表面的诸如光电导体的清洁目标物去除残留的调色剂颗粒。清洁装置包括清洁刷，电源电路和清洁构件。清洁刷包括刷旋转轴，并且电源电路将第一极性的第一电压施加到刷旋转轴。清洁部件将第一极性的第二电压施加到清洁刷。如果第一极性为负，则清洁部件静电地从清洁对象去除具有正极性的调色剂颗粒。然后，清洁刷通过与清洁对象接触而被摩擦带电到与第一极性相反的第二极性。因此，清洁刷也去除具有负极性的残留调色剂颗粒。因此，清洁装置除去正和负电荷的调色剂颗粒以清洁清洁目标。

摘要： A device for detecting viscosity of a liquid which varies with time includes a first tank provided with an overflow section for maintaining a predetermined liquid height, and a second tank fluidly communicated to the first tank and provided with a restricted outlet, or orifice. While a liquid is circulated through the two tanks by a pump, a height sensor which is dipped in the liquid in the second tank senses a liquid height in the tank in terms of capacitance. The output of the height sensor is representative of a viscosity of the liquid.
