Superior Technology to Make the Advanced Full Color Toner for Fine Image Quality
Abstract:It is effective to reduce the size of toner for fine image quality on electrophotographic system. But, in general, size production of toner is energy intensive. As its solution, the two technologies are proposed to make it possible to manufacture productively the fullcolor toners with smaller particle size in a dry process in the near future.
The mechanochemical method in a dry process of toner is introduced as the production of toner. This method is that the preground chips mixed with silica are ground using the pulverizer like a jet mill and is especially suitable to produce the color toners including high content of the wax. The size reduction of thus toners is especially hard in a dry process, but the specific energy consumption as grinding efficiency has been decreased up to half when using the mechanochemical method.
The grindability of the polyester resin as toner binder, which is main components of toner and controls the productivity of the toner, is also discussed. The specific energy consumption was decreased up to further half when using both high grindable resin and mechanochemical method.
It is proposed in this paper that both mechanochemical method and high grindable resin should be simultaneously applied as the process of size reduction of toner for fine image quality.

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.
