We have been researching the electrostatic particle conveyer that transports toner particles by using the electrostatic traveling field. In the single-component development system of electrophotography, by installing this particle conveyer on the development system, we constructed the new non-magnetic and non-contact single-component development system. In this research, we produced a mock-up machine, and the behavior of the toner particles in the development area was observed with a high-speed camera. In addition, the electric field distribution in the development area was calculated. The following findings were obtained from the experiment. i) The developed height of the toner pile increases in the increase of the development voltage, and saturates to approximately 30 pm. ii) The toner flies along the electric flux line in the vicinity of a pseudo-latent image. iii) The excess electric field at the edge of the latent image causes the deletion of the developed real image.
