[A]
While the drum rotates, the cleaning brush [A] distributes lubricant from the
drum lubricant bar [B] to the surface of the drum.
This mechanism improves the copy quality, especially for letter areas in full
color mode, since it helps the toner transfer to the transfer belt. It also
improves the efficiency of drum cleaning.
To apply the lubricant to the surface of the drum evenly, a straight-bristle
type is used for the drum cleaning brush.
