Abstract
Since the first cleaning member 24g scrapes off the foreign materials adhered to the corona charging electrode, and following that, the second cleaning member 24h wipes off the scraped foreign materials, the layered foreign materials firmly adhered on the corona charging electrode 22 is removed. Accordingly, image formation in electrophotographic apparatus or the like is suitably carried out, and image quality deterioration of the recorded image is suppressed.
Claims7
A corona generating apparatus for use in an electrophotographic copy machine, said apparatus comprising:
- (a) an electrode wire for charging corona therefrom;
- (b) a scraping device for scraping said electrode wire so that foreign materials adhering to said electrode wire are scraped therefrom;
- (c) a wiping device for wiping said electrode wire so that said foreign materials scraped from said electrode wire by said scraping device are removed therefrom;
- (d) a holding device for holding said scraping device and said wiping device;
- and
- (e) a supporting device for supporting said holding device so as to shift said holding device along said electrode wire.
