When a new toner is replenished to a developing device, the new toner is supplied to a developer carrier in a state of being sufficiently dispersed in the toner remaining in the developing device. A developing roller that carries toner T, a toner storage portion 43, a supply roller 44, and a partition wall 51 that partitions the inside of the toner storage portion into a supply side and a side where the supply roller is disposed. The wall projects downward from above the toner container, and the lower end is below the uppermost surface of the toner in the toner container. [Selection] Figure 1 |
