    • To provide a magnetic toner which is excellent in durability and developability even in the case of being applied to high-speed developing process or being used in a large-capacity process cartridge amount of toner in which is increased, and which has high degree of blackness. Provided is a magnetic toner having magnetic toner particles containing at least a binder resin and magnetic material particles each comprising a predetermined amount of a titanium compound, characterized in that: 1) the magnetic material particles have a predetermined amount of adsorbed moisture at a relative vapor pressure of 50%; and 2) a difference between the amount of moisture adsorbed to the magnetic material particles in an adsorbing process for increasing a relative vapor pressure and the amount of moisture adsorbed to the magnetic material particles in a desorbing process for reducing a relative vapor pressure is reduced.
    • 即使在应用于高速显影工艺的情况下也可以提供耐久性和显影性优异的磁性调色剂,或者用于大容量处理盒中的调色剂量增加,且具有高度的黑度 。 本发明提供一种磁性调色剂,其具有含有至少一种粘合剂树脂的磁性调色剂颗粒和各自包含预定量的钛化合物的磁性材料颗粒,其特征在于:1)磁性材料颗粒在相对蒸气中具有预定量的吸附水分 压力50%; 和2)降低相对蒸气压的解吸过程中吸附在相对蒸气压的吸附过程中吸附到磁性材料颗粒上的水分和吸附到磁性材料颗粒的水分之间的差异减小。
