PURPOSE:To obtain a sharp color image without staining a copying machine by using a combination of quinacridone and methine type colorants as a magenta colorant. CONSTITUTION:The methine type colorant having a bluish hue and superior saturation is used in addition to the quinacridone colorant in order to complement its a reddish hue and saturation. All the colorants are used in an amount of 2-20wt.%, preferably, 3-15wt.% of a binder resin, and a quinacridone to methine colorant weight ratio is 100:1-100:40, preferably, 100:3-100:20, thus permitting a sharp color image to be obtained without staining the surface of a silicone rubber fixing roller. |
