Magnetic one-component toner

摘要

In a magnetic one-component toner containing at least a binder resin, a charge control resin, and a magnetic powder, the charge control resin has a weight-average molecular weight of 1.5 x 10<4> or less, contains 8 to 15 % by weight of functional groups, and is added in 5 to 20 parts by weight to 100 parts by weight of the binder resin. This makes the toner highly safe for humans and the environment and excellent in fixability and electric chargeability.
