摘要：
A communication unit has a first conveyance part connected to a toner cartridge and provided with a feed port for a toner from the toner cartridge, and a second conveyance part connected to a developing device and provided with a replenishment port for a toner to the developing device. In a state locked by the lock mechanism, the first conveyance part and the second conveyance part are connected to each other, and the feed port of the first conveyance part and the replenishment port of the second conveyance part are opened, allowing for a toner replenishment. In a lock-released state, the feed port of the first conveyance part and the replenishment port of the second conveyance part are closed by a circular arc-shaped shutter member and a rotary shutter member, allowing the first conveyance part and the second conveyance part to be separable from each other.
