ABSTRACT:
A developing apparatus having a sealing mechanism for preventing a toner leakage is disclosed. A sealing member has a recess for receiving one end of a scraper rod. In the recess, an elastic sealing plate presses the end of the scraper rod against the peripheral surface of a thin film sleeve and seals the recess. Toner transported along the inner side face of the sealing member is scraped by the end of the scraper rod. The elastic member prevents the leakage of toner which has penetrated into the contact face between the inner peripheral surface of the sealing member and the outer peripheral surface of the thin film sleeve.
