ABSTRACT:
A two-component magnetic developer of the invention for printing characters on documents for magnetic ink character recognition comprises the mixture of 20 to 80 percent by weight of a magnetic toner containing binder resin and magnetic powder and the balance being a magnetic carrier, wherein the magnetic toner has magnetic powder of 30 to 60 percent by weight, residual magnetization .sigma.r of 4 to 16 emu/g and average particle diameter of 5 to 15 um. The developer rarely causes background fogging and carrier adhesion on the developed images which is suitable for MICR.
