Apparatus for minimizing toner contamination on an image formation member |
摘要 |
<p>To prevent deterioration of charge performance, which is caused by wear of a gap control member that keeps a charge roller (14) into non-contact with the image carrier, the charge roller is brought into contact with a surface of a photosensitive drum via a pair of tape members (18) as the gap control member that contacts with a coat and non-charge portion of the photosensitive drum. A gap (G) can be formed between an effective charge width portion of the charge roller and the surface of the photosensitive drum. <IMAGE></p> |
