PURPOSE:To obtain an image recorder capable of hot only ventilating a device and always maintaining it in constant conditions, but also preventing the entering of dust in simple structure. CONSTITUTION:An ventilation fan 330 is arranged in the vicinity of a heating drum 116 and moreover, an air blower 332 is arranged in the vicinity of a photosensitive material magazine 14 and an image receiving magazine 106, as well. The quantity of air supplied by the air blower 332 is set larger than that discharged by the ventilating fan 330. Therefore, a pressurizing (positive pressure) state is always obtained in a main body 12 and the dust is prevented from entering from the gap of the machine body 12. Therefore, the dust is never stuck to the image forming surfaces of the photosensitive material 16 and the image receiving material 108, so that an excellent image is formed and the dust never causes a failure in the operation of the device. |
