| titleOfInvention | Developing device and image forming apparatus |
| abstract | A developing device capable of forming a good image over a long period of time by minimizing fluctuations in toner density and developer bulk level in a trickle-type developing device using a two-component developer. Providing equipment. A developing device including a developing member that conveys and agitates a developer in a developing tank and a developer carrying member, a developer replenishing tank that replenishes the developing tank with a replenishing developer, a toner concentration detection sensor, and development. A discharge mechanism for discharging the developer in the developing tank, which exceeds the predetermined amount when the amount of developer in the developing tank exceeds a predetermined amount, the current toner concentration in the developing tank, and the reference toner concentration in the developing tank, The storage means for storing the corrected reference toner density calculated by (current toner density−corrected value), the predetermined replenishment amount to the developing tank, and the allowable value of the current toner density with respect to the reference toner density, and the corrected reference toner density are calculated. And control means for comparing the current toner density with respect to the reference toner density and the corrected reference toner density. [Selection] Figure 5 |
