PROBLEM TO BE SOLVED: To enhance mountability onto an apparatus body and general purpose performance while reducing cost by providing a driver circuit for applying a specified signal to a laminate electrode provided in order to generate ions at each intersection of first and second electrodes arranged in matrix. SOLUTION: The print head 50 has a head substrate 54 being fixed removably to a basic body 52 and a plurality of first electrodes (line electrodes) 56 and second electrodes (finger electrodes) 58 are laminated on the head substrate 54. A flexible printed board 60 connected with the head substrate 54 to apply a specified image signal to the line electrodes 56 and finger electrodes 58 and a driver circuit for applying a specified image signal to the line electrodes 56 and finger electrodes 58 through the flexible printed board 60 are mounted on the head substrate 54. A region W for discharging an ion flow 15 formed at intersection of the line electrodes 56 and finger electrodes 58 on the head substrate 54. |
