PROBLEM TO BE SOLVED: To provide a developing device capable of reducing fog by applying a sufficient amount of charges to even deteriorating toner. SOLUTION: The developing device 10 has a voltage application member 18 that is in contact with, via a toner layer, a developing roller 14 rotated holding the toner layer on its circumferential face. In the developing device, the voltage application member 18 applies a relatively low voltage to the upstream contact part and a relatively high voltage to the downstream contact part in the direction of the rotation of the developing roller 14.
