<p>PROBLEM TO BE SOLVED: To obtain a magnetic toner for an MICR(magnetic ink character recognition) printer excellent in image density and reading precision and excellent in dispersibility and durability. SOLUTION: The magnetic toner contains a resin binder and a magnetic powder contg. a 1st magnetic powder having 24-40 emu/g residual magnetization and a 2nd magnetic powder having 1 to <24 emu/g residual magnetization. The residual magnetization of the magnetic toner is >7.0 to 20 emu/g.</p> |
