Abstract

A cleaning solution is used to at least substantially remove colorant from the photoconductive drum as the photoconductive drum rotates. A wiper wipes the cleaning solution from the photoconductive drum while purposefully maintaining a layer of the cleaning solution on the drum. The wiper has an edge that is purposefully rounded.
