PROBLEM TO BE SOLVED: To provide an electrophotographic copying device for preventing the oxidation of the surface of a photoreceptor without providing a heating means used only for the photoreceptor, irrespective of a simple constitution. SOLUTION: The photoreceptor drum 22 is heated by arranging an air sending path 11 and sending the air 7 heated by the waste heat of a fixing roller 9 to the photoreceptor drum 22. Besides, toner on a recording medium is also heated by switching the direction of a switching means 37. Thus, by using the waste heat of the fixing roller 9, it is unnecessary to install the heating means used only for the photoreceptor drum 22, so that simply constituted, inexpensive products are provided. |
