Zusammenfassung:PROBLEM TO BE SOLVED: To prevent dew condensation on a part due to water vapor produced from a recording medium even in an image forming apparatus whose warm-up time is comparatively short. SOLUTION: A carrying-out side insertion hole 51B is made open by a shutter 54, and a fan 55 is driven to generate the flow of air in space R. Heat flow generated from a heating roller 52 rises to the space R via the carrying-out side insertion hole 51B. Meanwhile, the flow of the air is formed by inflow air generated from the fan 55 in the space R, and causes a Venturi effect, whereby the heat flow is positively taken in the space R so as to warm the space R in a comparatively short time.
