摘要： A developing device that efficiently adjusts the amount of charge on the developing agent without being affected by external conditions, and that continuously supplies a developing agent with the appropriate toner concentration and amount of charge. An ionized air flow adjusts the amount of charge on the developing agent discharged from the developing unit to improve the dispersability of the replenished toner without applying unnecessary stress. The developing agent is raised upwards by a screw, downwards by an agitation member, and then gathered by a screw in a circulating flow. Consequently, the developing agent is uniformly mixed within the developing agent agitation unit. This circulating flow of the developing agent increases the probability of contact and reduces damage to the developing agent. When the ionized air flow reduces the amount of charge before agitation, the toner can be uniformly charged to the appropriate value.

摘要： A developing device capable of mixing and agitating toner and a developing agent efficiently and without applying unnecessary stress, efficiently adjusting the amount of charge on the developing agent without being affected by external disturbing conditions, and continuously supplying a developing agent having the appropriate toner concentration and amount of charge in just the necessary quantity. The amount of charge on the developing agent discharged from the developing unit is adjusted (reduced) by an ionized air flow, so that it is possible to improve the dispersability of the replenished toner, and quickly adjust the appropriate amount of charge without applying unnecessary stress. The developing agent that is raised from below upwards by a screw is moved downward by an agitation member, and again gathered in around the screw in a circulating flow. In this way, the developing agent within the whole developing agent agitation unit is uniformly mixed. This circulating flow of the developing agent increases the probability of contact, and decreases the amount of damage to the developing agent. When the amount of charge is reduced before agitation using the ionized air flow, the toner can be uniformly charged up to the appropriate value.
