A cleaning device for cleaning residual toner that, in an image forming
device of an intermediate transfer type, remains on an outer
circumferential surface of an intermediate transfer member after a
transfer. The cleaning device includes: a charging brush operable to
contact with and charge the residual toner; and a cleaner that is
disposed downstream of the charging brush in a toner transport direction
of the intermediate transfer member, and is operable to electrostatically
adsorb the charged residual toner, wherein electrically conductive
bristles have been planted randomly in the charging brush to be
distributed evenly in density.
