ABSTRACT:
A magnetic toner having a specific surface area of not more than 3.0 m.sup.2 /g computed by the Brunauer Emmett Teller equation and the number of molecules of CO.sub.2 gas, being equal to 100
m.sup.2 to 1000
m.sup.2, adsorbed by the toner is provided. The triboelectrification of magnetic toner particles of the magnetic toner is uniformed by adjusting the magnetic toner using an impact force so that the specific surface area of the magnetic toner and the number of molecules of CO.sub.2 gas adsorbed by the toner are presented in the range described above.
