Abstract
We have studied the dynamics of toner and carrier particles in a two-component magnetic brush development system used for electrophotography in order to improve the image defect due to the bead-carry-out (BCO) phenomenon. It has been confirmed that developed toner particles on the photoreceptor increases and the number density of the adhered carrier particles decreases when the effective AC voltage superposed on the DC development voltage is high. Because the developed toner particles reduce the surface voltage of the latent image on the photoreceptor, the BCO is improved when the amount of developed toner particles is high.
