Abstract

PURPOSE:To simplify a constitution by fixing a detection electrode and vibrating an oscillator provided nearby. CONSTITUTION:Oscillators 4a, 4b are arranged opposed to each other as if to hold a detection electrode 2 facing a charged object 1 at the both sides between the oscillators. In a part near the charged object 1 of the width T of each oscillation piece, the oscillation pieces 4a, 4b are set directly opposed to each other and a detection electrode 2 is so arranged as to provide its side only to a part remote from the charged object 1. Then the oscillation pieces 4a, 4b are vibrated as if they were caused to approach or become distant from the oscillation pieces 4a, 4b. In this manner, the surfacial potential of the charged object 1 is measured.
