ABSTRACT:
A developer device for electrostatic copiers includes a housing in which toner is circulated. The circulating toner is dropped in free fall at a predetermined location. Underneath that location are two side-by-side lengthwise extending channels into which the falling toner is substantially uniformly distributed. Guide baffles in one channel direct the incoming toner along the channel in one direction, and guide baffles in the other channel direct toner in the opposite direction.
