摘要

A charging roller for use in a machine in which an electrical bias is applied to a surface of a member is provided. The charging roller includes a shaft, a foam material surrounding at least a portion of the shaft, and a thermoplastic material. The thermoplastic material surrounds at least a portion of the foam material. The foam material is adapted to provide for greater compliance to prevent vibration of the roller against the surface.
