A method and an apparatus are provided for cleanly cutting off filling of a container with toner without post-cutoff dribbling. The apparatus for the method includes (a) a conduit member having a discharging end; (b) a conveyor device for moving the toner from the hopper towards the container; and (c) a nozzle device including a positive and negative air pressure applying device, and a nozzle member for directing the toner to the container. The nozzle member has a first end connected to the discharge end of the conduit member and a second and opposite end for dispensing moving toner into the container. The nozzle member includes a post-cutoff controllable vibrator assembly connected to a controller for selectively enabling clean cutoff of powder flowing into the container without post-cutoff dribbling.
