CORONA DISCHARGE DEVICE, PHOTORECEPTOR CHARGER, AND METHOD FOR MAKING DISCHARGE PRODUCT REMOVING MEMBER
摘要:
A corona discharge device (10) comprises a discharge electrode (1) for causing electric discharge, a discharge product removing member (4) provided around the discharge electrode (1), and containing a material capable of removing a discharge product, and a shield plate (3) interposed between the discharge electrode (1) and the discharge product removing member (4), having a through-hole (3a) open toward the discharge electrode (1), and having a surface opposed to the discharge electrode (1) and at least the surface being made of a metallic material. With this, a corona discharge device, a photoreceptor charger, and a method for making a discharge product removing member which realize high trapping efficiency for discharge products and a long life of a discharge product removing filter are provided.
