OPENING/CLOSING MEMBER, DEVELOPER SUPPLYING APPARATUS, AND IMAGE FORMING APPARATUS

摘要

An opening/closing member is movable between an open position in which a passage opening through which developer passes is open and a closed position in which the passage opening is closed. The opening/closing member includes a protrusion that protrudes toward an edge of the passage opening with respect to a scrape limiting portion, the protrusion being disposed on each of two sides with respect to a direction that is perpendicular to directions of movement between the open position and the closed position. A front end of the opening/closing member in a closing direction from the open position to the closed position is disposed so as to be separated from a surface of the edge of the passage opening.
