ABSTRACT:
A toner cartridge for replenishing toner in a reproducing machine which may be readily inserted in an opening in a toner dispenser, includes a base plate and a toner hopper slidably engaged with the top of the base plate, both the base plate and the toner hopper having a plurality of apertures therein for toner to pass therethrough into the toner dispenser when in the open position. The base plate of the toner cartridge has a hook at one end adapted to lock under the lip of the toner dispenser opening when the cartridge is inserted in it, and the toner hopper has a hole at the opposite end adapted to lock under the lip of the toner dispenser opening when the toner hopper is slidably moved from the closed position to the open position. In the closed position portions of the base plate provide a seal under the apertures in the toner hopper and when the toner hopper is slidably moved to the open position, the apertures in the base plate and toner hopper are open permitting toner to fall into the toner dispenser. A preferred toner hopper comprises a plurality of bins each with a plurality of inclined sides defining a chute which terminates in the plurality of apertures in the bottom of the toner hopper. With this structure the toner cartridge dispenses toner only when in the locked position and is removable from the dispenser only when in the closed position.
