In the mono-component non-magnetic toner system, optimum toner charging and mass transfer are important factors to produce fine images with high quality. In previous work, we confirmed that a current flows through each system part (i.e. development roller, blade, and supply roller) during the roller rotation with toner attached on its surface. In this paper, we discuss the possible mechanism of generation of these currents in the development system. Development rollers having various surface properties were prepared for this study. It was found that the surface characteristics of the development roller considerably affected the value of the current. In particular the rate of charge decay of the roller surface strongly affected the current and also the toner charging. From these results, we propose a possible mechanism for this current generation.

  • 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.
