ABSTRACT:
A white toner comprising a fixing resin and dispersed therein, a titanium dioxide pigment of high purity containing at least 99% by weight of TiO.sub.2, not more than 0.1% by weight of Al.sub.2 O.sub.3 and not more than 0.05% by weight of SiO.sub.2 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 Al.sub.2 O.sub.3 and SiO.sub.2 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.
