In a sheet carrier of an image-forming apparatus, a gate, a carrier guide and a cover are cooled by air exhausted from an exhaust port of a guiding guide and an exhaust hole of the gate, and dew condensation is prevented. A recording paper where a full color toner image is fixed to one side is cooled by blowing the air exhausted from the exhaust port of the guiding guide and the exhaust hole of the gate against the recording paper. A pinch roller and a detection sensor are cooled by blowing the air exhausted from the exhaust port of the guiding guide and the exhaust hole of the gate against the pinch roller and the detection sensor. Since a heat of a fixing device is not absorbed by applying the air to the fixing device, no unnecessary surplus energy is consumed for maintaining a temperature required for fixing.
