Abstract
A toner cartridge is modified so as to improve the dispensing of toner through discharge ports extending longitudinally along the cartridge. A flexible flap member is secured external to the cylinder and overlies the ports so as to prevent toner from exiting the ports except along the preferred dispense zone, e.g., from the 4 o'clock to the 8 o'clock position.
