摘要

A developing device is provided with a developer containing section (526a,526b); a developing roller; a restriction blade (560,560a) for limiting the amount of developer carried by the developing roller; an end seal (527) for preventing the developer from spilling through (60th) a gap between an end of the restriction blade and the developer containing section and a gap between an end of the developing roller and the developer containing section; and a seal-assisting member (529) for pressing the end seal against the lateral end surface of the restriction blade, to reduce still more the amount of spoiling toner within an image forming apparatus. <IMAGE>
