The performance of rollers and belts used in roller-charging, development and transfer sub-processes of electrophotography is known to depend critically on the dielectric relaxation of the semiinsulating layer on the devices. The dielectric relaxation in turn requires efficient charge injection from the biased substrate. Taking into consideration the non-Ohmic nature of the electrical contacts, and the space-charge effects in the transport of injected charges, the impacts of charge injection on dielectric relaxation, and hence, on the device performance are analyzed theoretically. The results of analyses are confirmed by comparing with experimental current and voltage measurements in a characterization technique known as Electrostatic Charge Decay (ECD) method, on samples in use commercially.

  • 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.
