ABSTRACT:
An image forming device includes a device main body having a developer receiving port, and a developer discharge unit having a developer discharge port. When the developer discharge unit is attached to the device main body, the developer receiving port and the developer discharge port overlap each other. As the developer discharge unit is attached to the device main body, a shutter opens in a direction that is different from an attaching direction of the developer discharge unit. The developer discharge port of the developer discharge unit is opened accompanying an opening movement of the shutter, and an opening portion of the developer discharge port and an opening portion of the developer receiving port overlap each other at all times.
