清洁装置、图像形成装置、清洁装置的控制方法
摘要：
本发明提供清洁装置、图像形成装置、清洁装置的控制方法。清洁装置(70)包括：将清洁辊(62)的位置在与带电辊(61)接触的位置和与带电辊(61)分离的位置之间进行切换的接触分离机构(63)；和在感光体(11)旋转时，将向带电辊(61)施加的电压从DC电压切换为AC电压的电压切换部(71)。接触分离机构(63)，在带电辊(61)被施加AC电压时，使清洁辊(62)与带电辊(61)接触。由此，能够提高对带电辊的清洁性能。
摘要（英）：

The invention provides a cleaning device, an imaging forming device, a control method for the cleaning device. The cleaning device (70) comprises: a contact separating mechanism (63) for shifting the position of the cleaning roller (62) between the position contacting to the electric roller (61) and the position separating from the electric roller (61); and a voltage shifting portion (71) for shifting the voltage applied by the electric roller (61) from the DC voltage to the AC voltage while the photoreceptor (11) is rotating. The contact separating mechanism (63) contacts the cleaning roller (62) to the contact separating mechanism (63) while electric roller (61) is applied to the AC voltage. Thereby, the invention can enhance the cleaning performance for the electric roller.
