Toner Charging Characteristics Dependence on Different Charging Carrier Properties
Abstract:The charging of toner particles in contact with carrier or developing roller is the typical tribocharging method applied in the two-component development system. Control of toner charge is critical in maintaining good image quality in electrophotographic printing process. As such, understanding of triboelectric charging in the developer is important. The Technical Committee of The Imaging Society of Japan (ISJ) has introduced standard four types of carriers to estimate the specific toner charge which helps to align them in the triboelectric series according to the charging tendency. Hence, the toners which are slightly different from the surface treatment are triboelectrically charged with the standard carriers. The toner charge and the aerodynamic size of toner particles are measured simultaneously by the Electrical Single Particle Aerodynamic Relaxation Time (ESPART) analyzer to understand the charging tendency of carriers. Further, the correlation between film surface voltages charged by contact with carriers and the toner charge are discussed.

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.
