(Prior Art) Conventionally, a static eliminator for removing static electricity of a charged body is used by attaching an electrostatic copying machine, a facsimile or the like. For example, as shown in FIG. It is known that a plurality of conductive fibers b are held in a direction perpendicular to the charged body X and are grounded via a conductive wire c extending from the conductive body a. The static eliminator moves the charged body X in contact with or close to the conductive fiber b and moves the charged body X to generate air ions by using the electrostatic energy of the charged body X. The electric field from the charged body X is grounded. Collected in the conductive fibers b, and the air is ionized by the electric field to generate air ions. The air ions neutralize the charge of the charged body X.

端放電によって自己放電し易く効果的とされている。
In this type of static eliminator, the cut end d of the conductive fiber b is opposed to the charged body X, and the electric field is concentrated on the cut end d so that the self-discharge easily occurs due to so-called tip discharge.

Further, the conductive fiber b of the static eliminator is vertically held by the conductor a, and when the conductive fiber b comes into contact with the charged body X, the conductive fiber b is freely bent and the shape of the charged body X or its unevenness is obtained. It is possible to eliminate static electricity evenly.

However, the conductive fiber b has a disadvantage that the conductive fiber b may come off or be cut when the charged body X is contacted and the conductive fiber b is bent during static elimination. Further, since the bundle of the conductive fibers b must be held in the conductor a in the vertical direction, it is difficult to firmly fix the bundle to the conductor a, and therefore the conductive fibers b cannot be removed. . When the static eliminator is attached to an electrostatic copying machine or a facsimile,
Due to the conductive fibers that have fallen off, there is the inconvenience of causing image stains and malfunctions of semiconductor components.
