Patent ID: 6856779

Claim:
A toner cartridge removably attachable to a printer having a toner-receiving section, the toner cartridge comprising: a toner chamber that holds toner therein; and a toner-discharging mechanism mounted to said toner chamber and having a recess formed therein, said toner-discharging mechanism being movable between a first position and a second position; wherein when said toner-discharging mechanism moves to the first position to substantially close said toner chamber so that the toner does not leak from said toner chamber into the toner-receiving section, the recess faces an inner space of said toner chamber so that the recess holds a fraction of the toner; wherein when said toner-discharging mechanism moves to the second position to substantially close said toner chamber so that the toner does not leak from said toner chamber into the toner-receiving section, the recess faces an inner space of the toner-receiving section so that the recess discharges the fraction of the toner into the toner-receiving section.
