A particle charging device is described in which discharge electrodes and opposite electrodes are disposed in an opposed relationship, third electrodes being provided in the proximity of each discharge electrode. A high voltage source is provided for applying a periodically varying high voltage between the discharge electrodes and the third electrodes, a dc voltage source for applying a dc bias voltage between the above described electrodes, and a dc high voltage source for applying a dc high voltage between the third electrodes and opposite electrodes, whereby during the periods when the periodically varying high voltage is not applied between said discharge electrodes and the third electrodes, a dc corona discharge originating from the discharge electrodes may be always suppressed. Also an electric dust collecting apparatus making use of said particle charging device is disclosed herein.
