摘要：
A rotating cover (302) on the developer unit (34) of an imaging apparatus to prevent toner leaks from the toner entry port (205) of the developer unit. When installing a toner cartridge (35), the cartridge contacts a surface (312A) to cause the cover (302) to rotate to an open position, thereby exposing the toner port for receiving toner. Conversely, when the toner cartridge is removed the cover is rotated into a closed position with the aid of a torsion spring (308) so as to seal the toner entry port of the developer unit.
