Abstract
A rotating cover on the developer unit of an imaging apparatus to prevent toner leaks from the toner entry port of the developer unit. When installing a toner cartridge, the cartridge contacts a surface to cause the cover 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 so as to seal the toner entry port of the developer unit.
