Abstract

Experimental and numerical investigations have been carried out on the bead-carry-out phenomenon of electromagnetic bead chains in two-component development process of electrophotography. Electrostatic pull-off characteristics were measured in a magnetic field and then it was clarified how the critical pull-off field intensity to break chains and the amount of pulled-off carriers depended on the bead diameter and the magnetic field. Magnetic bonding force and electrostatic pull-off force were estimated numerically to discuss these experimental results. It was clarified that the bead-carry-out phenomenon can be predicted qualitatively from the comparison of calculated magnetic force and electrostatic force.
