Document Type and Number:
WIPO Patent Application WO/2017/212688
Kind Code:
A1
Abstract:
This charging device (2) is provided with: a first counter electrode (21) and a second counter electrode (22) arranged so as to be mutually facing; a discharge electrode (23) arranged between the first counter electrode (21) and the second counter electrode (22); and a power supply unit (10) for applying an AC voltage to at least one of the first counter electrode (21), the second counter electrode (22) and the discharge electrode (23). A first period and a second period are periodically repeated, wherein during the first period a first charging region (211) is generated between the first counter electrode (21) and the discharge electrode (23), and a first non-charging region (221) is generated between the second counter electrode (22) and the discharge electrode (23), and during the second period a second non-charging region (212) is generated between the first counter electrode (21) and the discharge electrode (23), and a second charging region (222) is generated between the second counter electrode (22) and the discharge electrode (23). Particles (90) are charged to the same polarity at the first charging region (211) and the second charging region (222).
