Abstract: In unipolar charging, a discharge current value at which charging efficiency is best and a discharge current dependency of multivalent charging differ depending on the particle size of the particles that are the object of charging. Therefore, for each particle size, a discharge voltage at which univalent charging efficiency is best and a discharge voltage at which the signal-to-noise ratio of a signal when particles of a different size are regarded as noise is best are obtained through experiment and stored in a storage unit (21). When scanning a classification voltage that is applied to a classification unit (32) of a DMA (3) to measure particle size distribution, a system controlling unit (2) acquires an optimal voltage corresponding to a particle size from the storage unit (21), and in conjunction with scanning of the classification voltage, controls a discharge power source (11) via a discharge voltage controlling unit (10) so that the discharge voltage is scanned in accordance with changes in particle size. It is thereby possible, for example, to reduce the amount of multivalent charged particles of different particle sizes that are mixed in with particles with a predetermined particle size that are extracted by classification, and to accurately determine the particle size distribution.
