Non-contact developer seal

摘要

A sealing apparatus in a magnetic brush development device is located in a non-contact fashion between the photoconductor drum and the magnetic brush roll. The seal has a plurality of ridges along the length of the seal that creates a differential air flow under the rotating photoconductor drum. This differential air flow prevents toner dust and bead carryout from axially migrating past the end of the photoconductor and magnetic roll.
