Abstract:
An electrification apparatus for providing electrification to a photosensitive body in an electro-photography, comprising:a first magnet including a magnetized base body obtained by magnetizing a base body of the photosensitive body or a magnet provided inside of the base body of the photosensitive body; a second magnet disposed outside the photosensitive body for opposing to said first magnet with a space to be magnetically levitated by said first magnet; and a discharge electrode attached to a face of the second magnet opposed to a surface of the photosensitive body, the discharge electrode being arranged with a predetermined distance from the photosensitive body surface and being configured to electrify the photosensitive body surface, wherein said space between the first and second magnets is adjusted by changing an intensity of magnetic poles of the first and second magnets to adjust the distance between the discharge electrode and the photosensitive body.
