摘要： A developing device includes a development roller (11), a magnetic roller (12), a transformer (83), a switching portion (81), output control portion (80) and a capacitor (82). The development roller (11) is opposite a photoconductor drum (42). The magnetic roller (12) performs, with a magnetic brush, the supply of a toner to the development roller (11) and the removal of the toner. The transformer (83) generates an alternating-current voltage applied to the development roller (11). The switching portion (81) passes and interrupts a current to the transformer (83). The output control portion (80) stepwise changes, when a duty ratio in switching is changed, the duty ratio a plurality of times from a first duty ratio to a second duty ratio. The capacitor (82) has one end connected to the transformer (83) and the other end connected to the switching portion (81).

摘要： A developing device includes a developing roller, a magnetic roller, a capacitor, a transformer, and a switching portion. The magnetic roller supplies toner to the developing roller or takes off the toner from the same. The capacitor is connected to a primary of the transformer, and the developing roller is connected to a secondary of the same. During a period while the voltage between electrodes of the capacitor is changing, the switching portion changes the duty ratio in a predetermined second time slot in which current flowing in the switching portion is smaller than that flowing in a first time slot.
