Abstract

PURPOSE:To give sharp magenta color and to enhance lightfastness resistant to discoloration due to light by incorporating a specified pigment as a colorant. CONSTITUTION:A combination of a quinacridone type pigment and a xanthene type dye or a pigment obtained by chelating xanthene type dye is incorporated in a toner as the colorant. The quinacridone type pigment, such as CI Pigment.Violet 19, CI Pigment.Red 122, or CI Pigment.Red 207, is used, preferably, in an amount of 0.2-20pts.wt., especially, 0.5-10pts.wt. based on 100pts.wt. the binder resin. The xanthene type dye, such as CI Solvent.Red 49, 52, or 108, is used, preferably, in an amount of 0.2-20pts.wt., especially, 0.5-10pts.wt. based on 100pts.wt. the binder.
