Electrification device, process cartridge, and electrophotographic image forming apparatus

An electrophotographic image forming apparatus comprising a charging apparatus, the charging apparatus comprising:

• a plasma actuator,
• wherein the plasma actuator comprises:
• a dielectric;
• a first electrode provided on a first surface of the dielectric;
• and
• a second electrode disposed with the dielectric interposed between the first electrode and the second electrode,
• wherein when an AC voltage is applied between the first electrode and the second electrode, the plasma actuator generates an induced flow from an edge of the first electrode along an exposed portion of the first surface of the dielectric which is not covered by the first electrode,
• the plasma actuator is disposed such that the induced flow is directly supplied to the surface of the body to be charged, and
• a DC voltage is applied between the first electrode and the body to be charged.
