高速電子写真技術のためのコロナ帯電方式の改善 Improvement of Corona Charging System for High Speed Electrophotography
For the purpose of improving the speed of the charging process of electrophotography, a new electrode system was investigated. The system consists of a blade electrode and a metal drum coated with a polymer film. The sharp edge of the blade electrode was retained perpendicularly for the drum surface by opening 2 to 6 mm gap. In order to prevent spark discharge, an 8 MΩ resistor was inserted between the blade and a dc high voltage source, and a glow-like discharge was observed in the space between the blade edge and the surface of the polymer film. As the discharge current obtained by the present electrode system was much higher than that obtained by a single wire corona charger, the charging speed attained by the present system was 7.2 times as fast as the case of the corona charging system.
