Zusammenfassung:In a developing device including a developer tank and a developing roller, an internal space of the developer tank is divided by a partition wall into a first conveying path, a second conveying path, a communication path and a pumping path. In the pumping path, there is disposed a developer pumping section including a pumping spiral blade, a pumping rotation shaft member, and a pumping gear. A developer in the pumping path is pumped up by the developer pumping section, so that a part of the developer is moved to a side of the first conveying path while another part of the developer is moved to a side of the second conveying path.
