Abstract
A corona discharge device includes a corona discharge electrode, and a control electrode interposed between the corona discharge electrode and a target object to be corona discharged for controlling a surface potential of the target object. The control electrode includes a film coating processed portion with a conductive dry film coating and an unprocessed portion with no film coating formed in at least one of two end portions of the control electrode in a longitudinal direction of the control electrode. The unprocessed portion of the control electrode has an opening ratio smaller than that of the film coating processed portion.
Claims7
A corona discharge device, comprising:
- a corona discharge electrode;
- and
- a control electrode interposed between said corona discharge electrode and a target object to be corona discharged, said control electrode controlling a surface potential of said target object;
- wherein said control electrode comprises a film coating processed portion with a conductive dry film coating and an unprocessed portion with no film coating, and said unprocessed portion of said control electrode is disposed in at least one of two end portions of said control electrode in a longitudinal direction of said control electrode.
A corona discharge device, comprising:
- a corona discharge electrode;
- and
- a control electrode interposed between said corona discharge electrode and a target object to be corona discharged, said control electrode contorting a surface potential of said target object;
- wherein said control electrode comprises a film coating processed portion with a conductive dry film coating and an unprocessed portion with no film coating formed in at least one of two end portions of said control electrode in a longitudinal direction of said control electrode;
- and said unprocessed portion of said control electrode has an opening ratio smaller than that of said film coating processed portion.
