<p>A printer comprises an electronic photograph unit, which uses toner to develop an electrostatic latent image formed on a photosensitive member and transfers it to a sheet of paper, and an optical fixing device that fuses the toner image on the paper using intense radiation to fix the image. A preheating unit using a Peltier unit as a heat medium is arranged in a stage preceding the optical fixing device, and the paper and the passage are preheated by the waste heat from the Peltier unit to improve the performance of the optical fixing device. Cooled air from the Peltier unit is used to cool the optical fixing device and other units.</p> |
