The Effect of Silica Properties on Toner Charge and Printing Quality
Abstract:Toner is composed of binder resins, colorant, charge control agent, wax and external additives.
Several kinds of metallic oxides such as silica, titania and alumina are used for external additives. Especially, silica is added to the toner particle surface for the improvement of toner flow, the control of triboelectric charge and the reduction of adhesion force between toner particles and other materials. That is, silica is one of the most important affecting factors on the toner physical and chemical properties.
In this review, triboelectric charge and printing quality of toner were discussed with respect to the effects of various silica types. Various types of silica having different BET surface area, primary particle size and surface treating reagents were investigated for this review.
The optimum composition and desired type of silica to obtain better performance of the toner charging and printing quality were also designed.

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.
