Effects of Carbon Black on Toner Tribocharging in Two-Component Electrophotographic Developers
Carbon black was found to have the following effects on the triboelectric properties of model toners made from carbon black in a polymer binder:
1. Increasing the carbon black content causes the absolute value of the charge-to-mass of model toners to decrease when the toner is charged positively or negatively using poly(methylmethacrylate) coated carrier or poly(vinylidine fluoride) coated carrier.
2. The ratio of q/m when the toner is charged positively to q/m when the same toner is charged negatively is a constant.
3. Increasing the carbon black content causes the absolute value of the slope and the intercept of linear plots of mass-to-charge as a function of the mass ratio of toner to carrier to increase.
The model predictions agree with these observations.

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.
