PURPOSE:To reduce a danger of cutting of a wire to replace the wire easily by stretching the wire between feeding terminals of a printed circuit board and making the printed circuit board attachable to and detachable from an electrifier case. CONSTITUTION:Holes 72 and 73 where end parts of a wire 1 for electrostatic charge are held are provided in both end parts of a printed circuit board 71, and copper foil patterns 74 and 75 are formed on the surface of this board around these holes. The wire 1 has both end parts inserted into a pair of wire holding holes 72 and 73 of the printed circuit board 71 and a tension is applied to this wire, and the wire 1 is fixed onto copper foil patterns 74 and 75 in this state by soldering. An electrifier 8 has a case 81 where a printed circuit board unit 7 is stored, and the electrifier case 81 is provided with a board holder 82 for keeping the stored printed circuit board 7 vertical and two flat springs 83 which press the printed circuit board unit to this holder 82. When the electrifier 8 is attached to a prescribed position of an electrophotographic printer, a voltage is supplied to the wire 1 for electrostatic charge from a printer-side connector through a feeding terminal 76 of the printed circuit board unit 7. |
