ABSTRACT:
A cartridge for holding toner powder has an exit opening with a surrounding flange. When a cartridge is refilled for re-use the exit opening is closed by a sliding cover. In order to minimize the leakage of toner powder around the cover, a magnetic strip is secured on the flange surrounding the cover so that leaking powder will be attracted to the magnet.
