Abstract
PURPOSE:To obtain a toner with superior chargeability, durability, a superior hue, etc. by adding a compound belonging to C.I. Solvent Red 49, a compound belonging to C.I. Solvent Red 52 and the Cr complex of alkylsalicylic acid to a binding resin. CONSTITUTION:To a toner binding resin are added rhodamine base FB or other compound belonging to C.I. Solvent Red 49, ''Macrolex Red 5B '' belonging to C.I. Solvent Red 52 in consideration of other compound belonging to C.I. Solvent Red 49 and the Cr complex of alkylsalicylic acid by 0.1-5wt%, 0.1-10wt% and 2-10wt%, respectively to the amount of the resin. They are mixed, pulverized, melted, kneaded, cooled, pulverized, and classified. The resulting powder having 1-20mum grain size is mixed with colloidal silica and iron powder as a carrier to obtain a developer contg. a negatively charging magenta toner with a superior hue, superior chargeability, durability, etc.
