PROBLEM TO BE SOLVED: To stably form a good image whose the image gray level is not lowered and the image blurring or the like is not caused, even in the environment or a high temperature and high humidity without making the size of a device large. SOLUTION: This image forming device 200 is provided with at least a photoreceptor drum (image carrier) 2, a developing device 3, a transfer roller (transfer means) 5 for transferring a visible image formed on the drum 2 to a transfer material P, a fixing device (fixing means) 6 for fixing the visible image on the material P, a component mounted substrate 201 mounting an electric circuit and a fan 206 for cooling the device. In this case, the fan 206 is arranged above the board 201, an air duct is formed through the fan 206 from the outside of the device main body to the inside, air flowing the air duct passes through the substrate 201 and the device 6 and is exhausted to the outside of the device main body and the device 6 is arranged in the downstream side of the drum 2 and the device 3 with respect to the direction of the flow of the air flowing the air duct. |
