Abstract
A high-quality end seal member which is easy to manufacture, 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 for inhibiting, at a desired acceleration, leakage of toner from end of rotating body using anti-leakage gap obtained by causing recessed region to be deformed toward rotating body is provided with sealing member having striped pattern comprising plurality of steps of linear configuration which come in contact with toner carrier, i.e. rotating body, of image-forming device. When toner conveyed by toner carrier comes in contact with radiused region at edge of projecting region of irregular surface of sealing member toner scraping angle is greater than toner angle of repose. Elastic body at back surface of sealing member is used to achieve reactive-force-providing elasticity for contact load between sealing member and rotating body.
