Abstract:
The static eliminator includes an ionizer including a power source and an electrode which applies ions to an electretized dielectric film to eliminate electric charges formed on the electretized dielectric film. The electrified substance is in an electrically non-grounded state when the electric charges on the electretized dielectric film are eliminated.
