Abstract: Exemplary embodiments provide charging systems and methods for effectively delivering charges onto a receptor. The charging system can include a low velocity gas stream, an emitter assembly for providing cathode-to-anode field bias to generate charges from the low velocity gas stream, and an emitter-to-receptor (e.g., photoreceptor) electric bias to enhance the charge delivery to the receptor. The disclosed charging systems and methods can be used to achieve an optimal charging performance at a low projected cost for any suitable receptor that needs to be charged. Exemplary receptors can include a photoreceptor (PR) such as a belt PR or a drum PR, a toner layer, a sheet of media on which toner can be deposited, or a transfer belt in an electrophotographic printing machine.
