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 (S) and an adjustment volume (ko&#xd7;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 (S). 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.

Changing the charging applied voltage control in an image forming apparatus based on an increase in the cumulative number of times of execution of image forming

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).
