PROBLEM TO BE SOLVED: To provide an image forming device capable of performing a quick image forming on both sides of a sheet material, and with which the accuracy relating to image forming is held stably over even a long period of time of usage. SOLUTION: A copying machine 200A is equipped with a cooling fan 10 and an exhaust duct 15 in the middle of the route of a transporting path 2a, and also equipped with a cooling fan 14 and an exhaust duct 16 near a guide 12 before and under a resist. The cooling fan 10 is for performing the ventilation in the middle of the route of the circulation transporting path 2a, and the exhaust duct 15 is a fluid passage communicating with the outside of the machine for discharging the air flow sent from the cooling fan 10 to the outside of the machine. The cooling fan 14 performs ventilation to the guide 12 before and under the resist, and the exhaust duct 16 is a communicative path to the outside of the machine for discharging the air flow sent from the cooling fan 14 to the outside of the machine. |
