Abstract
In accordance with the invention, there is an electrophotographic charging device including a first electrode, a second electrode adjacent the first electrode, a plurality of nanostructures adhering to the first electrode, and voltage supplies electrically connected to the first electrode and the second electrode, wherein the voltage difference between the first electrode and the second electrode creates a high electric field at the nanostructures to cause charge species generation that is deposited on a receptor.
