Abstract
This invention relates to an toner cartridge to dispense toner to a developing system in a photocopying device. The cartridge has a primary baffle thereby forming a main chamber and a dispensing chamber. The dispensing chamber is divided into a primary dispensing chamber and a secondary dispensing chamber by a secondary baffle. Apertures are formed in the container adjacent to the secondary dispensing baffle. The cartridge is designed to be rotated in one direction to fill the secondary dispensing chamber with toner, and then rotated in an opposite direction to dispense the toner from the secondary dispensing chamber through the apertures.
