摘要：
A developer agitator of an image forming device capable of improving the electrification rate of a developer is disclosed. The developer agitator includes a rotatable shaft and an agitating wing disposed on the circumferential surface of the shaft. The agitating wing has an uneven part formed to increase the contact area with a developer. The developer agitator can obtain an electrification rate of the developer required for high speed printing, thereby allowing the image forming device to be operated at a high speed.
