Experimental and Numerical Study on the Bead-Carry-Out in Two-Component Development Process in Electrophotography
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.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
