Interlocking magnetic developer roll assembly and method of manufacturing

摘要

A developer roll for use in an electrophotographic printing machine of the type having an electrostatic latent image recorded on a photoconductive member in which a magnetic field attracts magnetic particles to form a magnetic brush on the periphery of a developer roll assembly. The developer roll assembly includes a sleeve and the developer roll. The developer roll is located at least partially within the sleeve. The developer roll includes a core having a core feature and a magnetic member having a member feature. The core feature and the member feature cooperate with each other so that the member and the core are mechanically interlocked with each other.
