Development of Low-melt White Toner for High Image Quality and High-speed Printing

Abstract

While digital communication is accelerating in recent years, a shift to a digital printing machine is accelerated from an offset in print market. Fuji Xerox developed white toner for “Iridesse^TM Production Press ” which is higher model of “Color 1000i Press”. The ideal structure of white toner is that the white pigment is added in high concentration, uniformly dispersed internally and there is no pigment exposure to the surface. We examined a thin and uniform shell structure of toner. And, we applied Super EA-Eco low melt technologies to white toner. As a result, we have succeeded in developing white toner that is capable of the low temperature fixability, high whiteness/opacity and high transfer property.
