Study on Positively Chargeable Polyester Toner
Abstract:To apply polyester resin to positively chargeable toner, the relation between the acid value of its resin and toner charge, and also dispersion of charge control agent in low acid polyester resin were investigated. The mixing condition of polyester resin and charge control agent was also investigated for the most suitable positively chargeable toner. It was found CCA should be dispersed as certain aggregates, to get higher charging-up speed and the charge stability. That means low acid value of polyester does not always mean disadvantages, and we could make positively chargeable polyester toner with high durability, and low energy fusing.

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.
