Abstract
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.
