PROBLEM TO BE SOLVED: To provide a color image forming device provided with a cleaning unit that can bring a cleaning member always into stable contact with an image carrier in the case of separating the cleaning unit and bringing it into contact integrally. SOLUTION: In a cleaning unit 119, a fulcrum 206 is arranged at the rotational center of an auger 303, and the support point 206 is arranged in the acting direction of driving force in a driving transmission point 205. The support point 206 is so arranged that the increase direction of moment around the support point 206 caused by the movement of the center-of-gravity position of the cleaning unit 119, and the increase direction of moment around the support point 206 generated by the increase of driving force are different directions from each other. |
