Abstract
A charging device with a plate-like electrode having a plurality of protrusions, the charging device having a cleaning device including cleaning members which are positioned bilaterally to the electrode and grip the electrode therebetween to clean. The cleaning device cleans the electrode while the cleaning members slide on a guide formed along the electrode, or the cleaning device cleans the electrode by griping the electrode by the cleaning members which are positioned along the electrode.
Claims19
A charging device comprising:
- a plate-like electrode provided with a plurality of protrusions;
- a cleaning device including rotatable cleaning members provided bilaterally to said electrode and gripping said electrode therebetween to clean said electrode;
- and
- a guide member provided along said electrode so as to slidably guide said cleaning device thereon.
A charging device comprising:
- a plate-like electrode provided with a plurality of protrusions on its one end portion which confronts an image bearing member;
- and
- cleaning members provided bilaterally to and along said electrode and gripping said electrode therebetween to accomplish cleaning, the cleaning members extending to full length of the electrode.
A charging device comprising:
- a plate-like electrode provided with a plurality of protrusions on its one end portion which confronts an image bearing member;
- cleaning members provided bilaterally to and along said electrode and gripping said electrode therebetween to accomplish cleaning;
- and
- a system which causes said cleaning members to grip said electrode only when said cleaning members are moved from a base toward an edge of the protrusions of said electrode.
