PURPOSE:To obtain a magnetic toner good in tone, by containing 2 kinds of magnetic toners and a binder resin. CONSTITUTION:A magnetic toner superior in fixability, and capable of forming a sharp image high in density and beautiful in solid parts, by mixing 100pts.wt. binder resin, such as styrene-chlorostyren copolymer, 25-100pts.wt. mixture of a magnetic powder (A) having 1.0-6.0mum average particle diameter, and a magnetic powder (B) having 0.01-0.1mum average particle diameter in 1/9<=B/A<=3/2 mixing ratio, and <=20pts.wt. colorant, such as ''CI Direct Red 1'', and when needed, together with lubricant, fixing agent, fluidity giving agent, caking inhibitor, etc., and melting, kneading, and pulverizing them. |
