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.
