ABSTRACT:
A method and apparatus for delivering toner in sealed containers to a developing system in an electrophotographic machine. Toner is sealed in flexible containers which are connected in a belt-like manner so that toner can be supplied continuously in discrete amounts to the developing system. The belt of sealed toner containers travel from a toner supply housing to an extractor unit where the containers are opened, allowing the toner contained therein to fall to the developing system. The depleted toner containers continue to travel to a take-up member where they are stored. Generally, the depleted toner containers are removed from the take-up member and discarded when a new supply of toner is added to the toner supply housing. This sealed container system allows for a large supply of toner to be stored anywhere in the electrophotographic machine and for the toner supply to be replaced very cleanly.
