Non-contact developer seal.

摘要

A sealing apparatus (40) in a magnetic brush development device (20) is located in a non-contact fashion between the photoconductor drum (10) and the magnetic brush roll (30). The seal (40) has a plurality of ridges along the length of the seal (40) that creates a differential air flow under the rotating photoconductor drum (10). This differential air flow prevents toner dust and bead carryout from axially migrating past the end of the photoconductor (10) and magnetic roll (30).
