電子写真方式の画像形成装置の端部シール材

Japanese Patent JP5693789

B2

Provided is a high-quality end seal member which is easy to manufacture and economical, and which exhibits excellent sealing properties with respect to inhibiting the leakage of toner in a toner-handling device of an image-forming device. End seal member (1) for inhibiting, at a desired acceleration, leakage of toner from end (6d) of rotating body (6a) using anti-leakage gap (15) obtained by causing recessed region (2f) to be deformed toward rotating body (6a) is provided with sealing member (1a) having striped pattern (2c) comprising plurality of steps of linear configuration which come in contact with toner carrier (6), i.e. rotating body (6a), of image-forming device (5). When toner (7) conveyed by toner carrier (6) comes in contact with radiused region (3) at edge of projecting region (2d) of irregular surface (2a) of sealing member (1a), toner (7) scraping angle (8) is greater than toner (7) angle (7a) of repose. Irregular surface (2a) of striped pattern (2c) comprising plurality of steps has toner control angle (10) permitting toner (7) to be returned toward interior (6f) in rotational axis direction (6e) by rotation of rotating body (6a). Elastic body (11) at back surface (1e) of sealing member (1a) is used to achieve reactive-force-providing elasticity (11b) for contact load between sealing member (1a) and rotating body (6a).
