Abstract
Apparatus for priming the magnetic end seals in the developer of a xerographic-based copying or printing machine immediately on startup to quickly establish the seals and prevent initial escape of toner from the developer housing, the apparatus continuing to supply developer material to the end seals while the machine is operating, thereby to prevent seal degradation or loss resulting from use and wear.
