Abstract:
The charge assembly according to the present invention includes a charge member having a conductive support body on which a resistance adjusting layer and a surface layer covering the resistance adjusting layer are formed, to rotate a surface of the image support body to electrically charge the image support body, the surface layer having a static friction coefficient of 1.0 or more; and a cleaning member rotating the surface layer of the charge member in contact therewith to remove foreign particles on the surface layer.
