Abstract:
A cleaning device including a conductive member configured to charge powder remaining on a member to be cleaned so as to have a single polarity and configured to scrape off at least part of the powder, and disposed to contact with the member to be cleaned; a cleaning member configured to electrically adsorb the powder present on the member to be cleaned, disposed to contact with the member to be cleaned and located downstream of the conductive member in a direction in which the powder is conveyed thereon; a first recovering member configured to electrically adsorb the powder present on the cleaning member and disposed to contact with the cleaning member; and a second recovering member configured to scrape off the powder from the first recovering member and disposed to contact with the first recovering member, wherein the conductive member is constant-current controlled.
