Abstract
In image forming apparatus using a heat-developable image forming sheet which is normally non-photosensitive but can be rendered photosensitive by preheating and is exposed to a light image to form a latent image and then heat-developed to produce a visible image, first heating means for preheating, exposure means for exposing the image forming sheet to the light image and the second heating means for heat development are respectively provided with fixing means for respectively fixing different image forming areas of the sheet at the processing positions of the respective means, and the first and second heating means and the exposure means are arranged so that the different image forming areas can be simultaneously processed by the respective means in parallel.
