摘要
Miniaturization, high sensitivity, there is provided an electric potential measuring device effective to realize high reliability. Electric potential measuring device is oscillating device (104) having an oscillating body which is supported to pivot by the oscillation torsion spring 102 and 103 and the spring; And a signal detecting unit (111, 112) disposed on a surface of the oscillating body. Whereby the capacitance between the detection electrode and the electric potential measuring object surface side is changed according to changes in distance therebetween by the oscillating device, the output signal appearing on the detection electrode is detected. ; Electric potential measuring device, torsion spring, the oscillating device, the detection electrode, the image forming apparatus
