    摘要: A developing agent comprising a toner particle containing a magnetic powder and a binder resin, the kinetic resistance of the developing agent being not higher than 200 M&OHgr;, and the absolute value of the difference &Dgr;V between the maximum value and the minimum value of the surface potential of the developing agent layer on a developing sleeve being not larger than 5V, is used for obtaining satisfactory developing agent image high in image density and low in fogging.

    摘要: A toner comprises a first particle having a predetermined volume average diameter and including thermoplastic binding resin and a colorant mixed into the thermoplastic binding resin to apply a color thereto. Wax of a second particle whose volume average diameter is considerably smaller than that of the first particle, is attached to the first particle by mechanical pressure. A nonmagnetic particle of a third particle is attached to the wax. The volume average diameter of the third particle is considerably smaller than that of the second particle. The attachment of the nonmagnetic particle decreases the area of an exposed surface of the wax, thereby preventing the wax from being attached to other wax and preventing the wax from contacting another toner.
