PROBLEM TO BE SOLVED: To prevent an ion wind occurring in a corona electrifier from disturbing the feeding of ink mist. SOLUTION: By arranging a corona electrifier 45 in a feeding path 48 of the ink mist 44 in a mist housing 41, and arranging the aperture part of a shielding case 45b through which the ion in the electrifier 45 is discharged on a downstream side in the feeding direction of the ink mist 44 fed to a control electrode 47 side by a fan 46, the feeding direction of the ink mist 44 is aligned with the direction of an ion wind occurring in the electrifier 45, the ion wind is prevented from disturbing the feeding of the ink mist 44, and the ink mist 44 is fed efficiently. |
