| Research Abstract |
Non-contacting surface resistivity tester has been developed using phi type corona electrode. The tester includes corona charger partly charge up the test material and surface charge sensor to obtain the motion of the surface charge. The equivalent circuit including the sensor and the test material indicates the relationship between the surface resistivity and the time variation of the surface potential. Experimental results shows the measurement of the surface potential and induction current can predict the surface resistivity for 10^6～10^9Ω and 10^9～10^<12>Ω, respectively.
