ABSTRACT:
According to the present invention, a magnetic toner comprising magnetic toner particles including at least a binder resin and magnetic particles is provided, wherein an isoelectric point of the magnetic particles is pH 4.0 or less, in order to provide a magnetic toner stably having an optimum charged amount regardless of environments so that a high-quality image having high blackness can be formed without causing any ghost phenomenon.
