Electrical Conductivity Measurements in Toners with Conductive Surface Additives
Abstract:The objective of this study is to establish correlation between toner conductivity measured in a pressed pellet, and conductive properties of an individual toner particle. Electrical conductivity of toners with conductive surface additives was measured as a function of applied voltage, pellet pressure and additive surface area coverage. Conductivity of toner pellets increases with additive surface area coverage in a percolation manner, and depends on additive-to-toner size ratio, and applied pressure. Possible sources of errors of pellet measurements include enhancement of inter-particle contacts and migration of the additives under high pressure.

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.
