PURPOSE: To prevent the occurrence of dew condensation on an image forming device main body and a guide plate constituting a sheets transfer path of a post processor when the post processor such as a sorter is connected to an image forming device and to display excellently a sheets transfer action even without providing a condensation preventive means in a paper ejector path in the image forming device main body. CONSTITUTION: The sheets transfer path 21 of the post processor 20 is connected to the paper ejection path 10 of the image forming device 1, and when a mechanism performing the action of sorting, etc., sheets in the post processor is constituted, a duct 25 is arranged on the sheets transfer path 21 of the post processor 20, and an exhaust fan is arranged on the duct, and air contg. vapor in the image forming device and the post processor is exhausted. Further, a means for improving transmission efficiency of the heat from the fixing device 3 of the image forming device to the guide plate of the paper ejection path 10 is constituted, and the guide plate of the sheets transfer path is heated. |
