Abstract

A magnetic brush developer having a toner dispenser cooperable with a removable toner container of the bottle type so that transfer of toner to the dispenser occurs without spillage or exposure of the toner to the external environment. The bottle and dispenser have mating interfaces which must be properly located, and then rotated, before dumping of toner from the bottle to the dispenser can occur. The dispenser interface is positioned in a slidable cover so that the bottle's toner content can be evenly distributed along the length of the dispenser, this length corresponding substantially to the length of the developer's development zone.
