PURPOSE:To realize an inexpensive and simple printing method, by electrophotographically copying image information on a coating material made of a fluorocarbon resin by using insulating toner and obtaining a negative by thermally transferring the image information as a mirror image onto a conductive supporting body by putting the coating material on the conductive supporting body. CONSTITUTION:When image information is electrophotographically copied on a coating material 1 made of a fluorocarbon resin, a toner image 1 appears as a normal image. When the coating material 1 and a conductive supporting body 3 are put together with the toner image 2 inside and they are heated after they are put between heat rolls 4 and 5, the toner image 2 is thermally transferred onto the conductive supporting body 3 as a mirror image to the image information. Since the photoelectrical toner is an insulating body, the transferred toner image 2 is insulating one and an attract toner thereafter when it is electrostatically charged. The insulating mirror image 2 on the surface of a negative 6 is electrostatically charged with static electricity by means of an electrifier 9 and the toner is developed by means of a developing device 10, and then, the toner 12 is transferred as a normal image onto transfer paper 7 by means of a transferring device 11. |
