  • Patent number: 3946230
    Abstract: An original and a heat sensitive member are inserted as a sandwich into a copying machine and fed past a combined imaging and transfixing or fusing station where radiation is applied to the sandwich to thermally impart a latent image of the original to the heat sensitive member. Thereafter, the original is separated from the heat sensitive member and ejected from the machine. The heat sensitive member on the other hand, continues onwardly to a developing station where toner particles are applied to develop the latent image. Next, the heat sensitive member loops back towards the imaging and transfixing station, and a copy medium is brought into engagement with the developed image. The copy medium and the heat sensitive member are then passed into the imaging and transfixing or fusing station.
