lowering of the image quality. Therefore, scraping off of this residual toner is required. This residual

Discharging is a process to return the photoconductive drum to its initial status before the next charging
process. Light is exposed in order to eliminate the charge remaining on the entire surface of the
photoconductive drum. With this process, the photoconductive drum can be arranged for the next
image forming.
