Corona discharger

Abstract

Abstract PURPOSE:To generate a correcting signal through simple constitution and perform current detection effective for destaticizing of a photosensitive body and transfer paper by a detection electrode by leading the correcting signal for correcting a reactive current out of the resonance capacitor of a leakage transformer. CONSTITUTION:The leakage transformer 3 is generally represented by a pi type equivalent circuit and simplified by hevenin's theorem; and a common capacitor C33 is connected for the purpose of output waveform shaping, a rise in output voltage by magnetism increase effect, etc., and a current leading the output voltage V0 by 90 deg. flows through it. This current is detected by a resistance 72 as a voltage to obtain the correcting signal for the reactive current flowing through the capacity of a corona discharger 5. The detection electrode 53 for detecting only a corona discharging current effective for destaticizing of the photosensitive body is arranged outside of a recessed type shield plate 51 and near the photosensitive body 6, and its detection signal is mixed with the correcting signal by a comparator 82 to remove the reactive current component.
