1. A developer unit for an image forming apparatus, comprising:
a developer device having a developer roller, which rotatably carries a developer agent on a surface thereof, a supplier roller, which supplies the developer agent to the developer roller, and a restricting member, which scrapes the surface of the developer roller to restrict thickness of the developer agent on the surface of the developer roller; a developer agent container, which contains the developer agent; and a plurality of conveyers, including a first conveyer and a second conveyer, to convey the developer agent in an axial direction of the supplier roller, both of the first conveyer and the second conveyer being disposed between the supplier roller and the developer agent container along a vertical direction of the image forming apparatus, wherein a distance between the first conveyer and the supplier roller is substantially equal to a distance between the second conveyer and the supplier roller, wherein the second conveyer is arranged along a circumference of the supplier roller and arranged in parallel with the first conveyer, wherein the developer device is formed to have a first room to accommodate the first conveyer, a second room to accommodate the second conveyer, and a partition wall to divide the first room and the second room; and wherein the developer device is configured to have a level of the developer agent in the first room to be lower than a level of the developer agent in the second room when the developer roller, the supplier roller, and the first and second conveyers are driven. |
