摘要： A cleaning device 70 includes: contact and release system 63 which switches a position of a cleaning roller between a position where the cleaning roller 62 is in contact with a charging roller 61 and a position where the cleaning roller 62 is separated from the charging roller 61; and a voltage selecting section 71 which switches a voltage to be applied to the charging roller 61 from a DC voltage to an AC voltage during the rotation of a photoreceptor 11. The contact and release system 63 brings the cleaning roller 62 into contact with the charging roller 61 at the application of the AC voltage to the charging roller 61. This makes it possible to enhance performance on cleaning of the charging roller.

摘要： As outermost coating-like layer(s) of charging roller(s) is or are made to contact and/or slide against photosensitive drum(s), charge is applied from the outermost coating-like layer(s) to the photosensitive drum(s), charging the photosensitive drum(s). This being the case, resistance of the outermost coating-like layer(s) of the charging roller(s) fluctuates, and surface(s) thereof become scratched and so forth, and gradually deteriorate. Moreover, if remedial action is not taken, charging capability of the charging roller(s) may decrease, leading to nonuniformity in charging of the photosensitive drum(s) and causing lowering of image quality and/or reduction in service life of the photosensitive drum(s). The outermost coating-like layer(s) of the charging roller(s) is or are therefore periodically stripped off therefrom to rejuvenate the charging roller surface(s).
摘要翻译：由于充电辊的最外面的涂层状层被接触和/或滑动抵靠感光鼓，所以将电荷从最外面的涂层形式施加到感光鼓（ s），给感光鼓充电。在这种情况下，充电辊的最外层涂层的电阻波动，其表面被刮伤等，并逐渐劣化。此外，如果不采取补救措施，充电辊的充电能力可能降低，导致感光鼓的充电不均匀并导致图像质量的降低和/或感光鼓的使用寿命的降低（s）。因此，充电辊的最外面的涂层状层因此被周期性地剥离，以使充电辊表面恢复活力。

摘要： When image forming is performed by a photosensitive drum according to operating conditions corresponding to an image forming mode selected out of a predetermined plurality of candidates, an actual cumulative number of printed sheets Pi is corrected and recorded based on the image forming mode (monochrome mode or color mode; low-temperature and low humidity ambience mode or other ambience mode) selected at the time of each image forming (S7) and an adjustment volume (ko×Pia) of a charging applied voltage Ey is calculated and the charging applied voltage Ey is set based on a corrected cumulative number of printed sheets Pia (S5). As a result, the charging applied voltage Ey to a charging unit is changed according to a cumulative number of printed sheets and at the same time, a pace of change thereof is adjusted based on the image forming mode.
