Abstract
PURPOSE: To perfectly remove the residual developer on a developing roller by providing an auxiliary separator below the separator.
CONSTITUTION: Not all the developer on a developing roller 14B is scraped by a separator 14E but part remains. Since no magnetic force acts near the end of the separator 14E, this residual developer falls by gravity from the developing roller 14B and sticks on the developing roller 14B. To prevent this, an auxiliary separator 52 is provided below the separator 14E. The leading end of the auxiliary separator 52 is positioned in proximity to the surface of the developing roller 14B, on the side of photosensitive drum 10, than a perpendicular line 51, and the trailing end thereof is held inclined downward. The developer falling between the developing roller 14B and the separator 14E flows down on the auxiliary separator 52 even if it receives the effect of the magnetic force of a magnet 12B2 on the way.
