ABSTRACT:
A thermal developing unit in a photocopier in which a latent image is formed on a photo-sensitive material which is then pressed between an endless belt and a heating drum to be thermally developed. In order to maintain the correct temperature on the heating drum, the drum and belt are rotated during a warm-up period or whenever a long sheet of photo-sensitive material is being used. Alternatively, the endless belt can be made of a material having a low heat capacity.
