portion 40h and a brush base 40v, and (2) a brush 47 attached on the brush base 40v.
The brush 47 can be made as a result of folding a brush member in the brush base
40v. The brush member is made from bristles such as nylon fibers or carbon fibers or
other fibers wound on a core material. A problem caused by an electrostatic
phenomena because of a friction of the brush 47 can be prevented if materials
comprising the carbon fibers are used for the bristles of the brush 47.
