发明名称 Weisser Toner.
摘要 A white toner comprising a fixing resin and dispersed therein, a titanium dioxide pigment of high purity containing at least 99% by weight of TiO2, not more than 0.1% by weight of Al2O3 and not more than 0.05% by weight of SiO2 as a white pigment. The white toner has markedly improved hygroscopicity as a result of using the white pigment in which the contents of metal oxides such as Al2O3 and SiO2 are reduced to very small amounts. The toner can thus retain the stable and uniform amount of triboelectric charge, and permits effective circumvention of troubles such as the reduction of image density, background fog and image blurring.
