<P>PROBLEM TO BE SOLVED: To provide a discharge irregularity observation method for obtaining a member making use of discharge or an charge phenomenon by the discharge which is developed on the basis of knowledge obtained by measuring microscopic electrical property and in which no irregularity in density or no void occurs. <P>SOLUTION: The discharge irregularity observation device is provided with a transparent electrode substrate 7 with a semi-transparent or transparent electrode 2 on a surface facing a roller member 1. The transparent electrode substrate 7 is installed so that an electrode surface can be brought into contact with or separated from the roller member surface. Then, a potential difference is provided between the transparent electrode substrate 7 and a metal core of the roller. Discharge light occurring due to the potential difference provided between the transparent electrode substrate 7 and the roller member 1 is photographed by a photographic device 3 installed on a back side of the transparent electrode substrate and the discharge irregularities occurring in the roller member are observed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
