Electrical Characterization of Transfer Media for Electrophotography
Abstract:A novel technique has been devised to characterize dielectric relaxation in transfer media, for better prediction of performance in electrostatic transfer of developed toners to receiving media. In this process, efficient dielectric relaxation in the media enables efficient transfer at moderate bias voltages. A recent theoretical analysis has shown that dielectric relaxation in transfer media is determined, not simply by sample resistance and capacitance, but more precisely by charge density, charge mobility and charge injection properties. In the new characterization technique, the observed decay of voltage over an electrostatically charged sample is interpreted in terms of these transport parameters. Results from representative media samples are presented and discussed.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
