ABSTRACT:
An improved developer roll magnet for a toner cartridge provides a strip of magnetic material that extends axially along a surface of the developer roll magnet located coaxially within a developer roll sleeve. The strip of magnetic material can be seated within a groove in the magnet and can extend radially outwardly above the surface of the magnet. The strip is generally adhered to the magnet by mutual magnetic attraction and can be made adjustable to move toward and away from the developer roll sleeve. The strip is typically located adjacent a nip formed between the developer roll sleeve and the image transfer drum of the cartridge to provide enhanced toner release for greater print yield and quality.
