    • A cleaning device disposed downstream from a transfer position in a direction of rotation of the image carrier to remove toner from the image carrier. The cleaning device includes a normally-charged toner cleaning member to electrostatically remove normally-charged toner from the image carrier, one of a polarity controller to control the toner on the image carrier to have a normal charging polarity and a reversely-charged toner cleaning member to electrostatically remove reversely-charged toner from the image carrier, a pre-cleaning member to electrostatically remove normally-charged toner from the image carrier, a pre-collection member to electrostatically collect the toner from the pre-cleaning member, and a control unit to reduce a voltage applied to the pre-cleaning member immediately after an untransferred toner image is removed from the image carrier by the pre-cleaning member below a voltage applied to the pre-cleaning member during removal of the untransferred toner image.
    • 一种清洁装置,其设置在图像载体的旋转方向上的转印位置的下游,以从图像载体中去除调色剂。 清洁装置包括常规充电的调色剂清洁部件,用于从图像载体静电去除正常充电的调色剂,极性控制器之一,用于控制图像载体上的调色剂以具有正常的充电极性,以及反向充电的调色剂清洁部件 从图像载体静电去除反向充电的调色剂,预清洁部件,以静电去除来自图像载体的正常充电的调色剂;预收集部件,用于从预清洁部件静电收集调色剂;以及控制单元 以在移除未转印的调色剂图像之后,将未转印的调色剂图像在预清洁部件从图像载体移除到低于施加到预清洁部件的电压之后立即降低施加到预清洁部件的电压。
