  • Publication number: 20190227447
    Abstract: A magnetic chemical toner comprising toner particles with high circularity (i.e., above 0.970) is described. The high circularity of the toner particles can maximize transfer efficiency and prevent toner waste during printing. The toner particles can comprise a polyester resin-based core. If desired, the toner particles can comprise a surface coating to modulate toner properties. Also described is a method of preparing the magnetic toner and a method of using the toner to print an image.
