Zusammenfassung:	PROBLEM TO BE SOLVED: To provide materials and methods for charging members with desirable surface, electrical, and/or mechanical properties to extend their usage life.SOLUTION: An embodiment includes: a conductive core 121; an outer base layer 123 having a surface roughness Rz ranging from about 0.1 μm to about 4 μm disposed over the conductive core 121; and an outer surface coating 129 disposed on the outer base layer 123 and including a plurality of conductive fillers combined with one or more polymers to provide the outer surface coating 129 with a surface roughness Rz of less than about 2 μm. The outer surface coating 129 provides desirable surface, electrical, and/or mechanical properties.
