In a charging time period T1, a dry electrostatic precipitator outputs DCON that is a current for charging a collection target object from a high voltage power supply. Subsequently, in a second period of time T2-2 after a first period of time T2-1 passes from a time that a charging pause time period T2 starts, the dry electrostatic precipitator outputs DCBC that is a current that is less than DCON and is greater than a current in the first period of time T2-1, from the high voltage power supply.
