PURPOSE: To provide an image forming device capable of suppressing backlash between rotary bodies such as a gear to a fixed range, even if the container of a developing device is flexed. CONSTITUTION: This image forming device is constituted so that a bearing 26 is provided on the tip of the rotary shaft of a developing sleeve 19 disposed in a developing container 22, to be concentric with the rotary shaft, the periphery of the bearing 26 is covered with a cover 26a, to be insulated and at the time of mounting the developing container 22 in the direction of the arrow E in the figure, the bearing 26 provided on the tip of the rotary shaft of the developing sleeve 19 is placed on a board 24a obtained in such a manner that a part of a driving side plate 24 supporting a driving gear for development 21 is louvered. Thus, a gear pitch P1 is kept. |
