Ionizer

An ionizer includes a discharge needle, a discharge needle holder holding the discharge needle, and a carrying air jet mechanism jetting out ion-carrying air toward a charge cancellation target. The carrying air jet mechanism is disposed at a position adjacent to the discharge needle holder, and it includes a drive nozzle having a drive air jet port, and a diffuser disposed in front of the drive nozzle with an ambient air suction gap interposed therebetween. A carrying air flow hole is formed inside the diffuser to be coaxial with the drive air jet port, and a carrying air jet port from which the carrying air is jetted out is formed at a fore end of the carrying air flow hole.

An ionizer includes: a positive-side transformer, and a negative-side transformer; a positive-side high-voltage output circuit that has a first input terminal and a second input terminal that are respectively connected to a ground terminal and a power supply terminal, the ground terminal and power supply terminal being provided on the secondary of the positive-side transformer, and also has a first output terminal from which a direct-current positive high voltage is output; a negative-side high-voltage output circuit that has a third input terminal and a fourth input terminal that are respectively connected to a ground terminal and a power supply terminal, the ground terminal and power supply terminal being provided on the secondary of the negative-side transformer, and also has a second output terminal from which a direct-current negative high voltage is output; and a discharge electrode connected to the first output terminal. The ground terminal in the positive-side transformer and the first input terminal in the positive-side high-voltage output circuit are mutually connected through an attenuating capacitor.
