The developing unit is configured to convert a latent image into visible form using a developer. The mixing container is separated from the developing unit and is configured to hold and mix part of the developer after use. The rotary feeder is configured to dispense the developer from the mixing container to a delivery path. The air pump is configured to supply compressed air to deliver the dispensed developer to the developing unit through the delivery path. The airflow regulator is located where the rotary feeder connects to the delivery path, and is configured to prevent the compressed air from flowing toward the rotary feeder from the delivery path.

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.

摘要翻译： 一种显影装置，其不会受到外部条件的影响而有效地调节显影剂上的电荷量，并连续地向显影剂提供适当的调色剂浓度和电荷量。 离子化空气流量调节从显影单元排出的显影剂上的电荷量，以改善补充调色剂的分散性，而不施加不必要的应力。 显影剂由螺杆向上升起，由搅拌构件向下升起，然后通过螺杆在循环流中聚集。 因此，显影剂在显影剂搅拌单元内均匀混合。 显影剂的这种循环流动增加接触的可能性并减少对显影剂的损害。 当电离空气流减少搅拌前的电荷量时，调色剂可以均匀地充电到适当的值。
