Abstract
Charging unit(s) is/are made versatile enough to be used in a plurality of image forming apparatus models having different processing speeds. Furthermore, in the context of an electrophotographic image forming apparatus permits selective switching between/among processing speeds, two charging unitshaving mutually identical configuration (e.g., charging units having case width 14 mm) are arranged within a single image forming unit (e.g., black image forming station Sa), the number of these two charging unitsthat is/are driven being switched in correspondence to processing speed(s) so as to make it possible for all of the charging units at image forming apparatusto be accommodated by the same model.
