Patent ID: 7903995

Claim:
A cleaning device which removes and recovers powder remaining after image formation on a member to be cleaned, with being mounted to an image forming apparatus performing image formation using coloring powder, the cleaning device comprising: a conductive member configured to charge the powder remaining on the member to be cleaned through application of a predetermined voltage so as to have a single polarity and configured to scrape off at least part of the powder remaining on the member to be cleaned, the conductive member being disposed so as to be in contact with the member to be cleaned; a cleaning member configured to electrically adsorb the powder present on the member to be cleaned through application of a predetermined voltage, the cleaning member being disposed so as to be in contact with the member to be cleaned and located downstream of the conductive member in a direction in which the powder is conveyed on the member to be cleaned; a first recovering member configured to electrically adsorb the powder present on the cleaning member through application of a predetermined voltage, the first recovering member being disposed so as to be in contact with the cleaning member; and a second recovering member configured to scrape off the powder from the first recovering member through application of a predetermined voltage, the second recovering member being disposed so as to be in contact with the first recovering member, wherein the conductive member is constant-current controlled.
