The lamp heater is formed from a nicrome wire stretched between clamp terminals, a silica tube and ceramic holders closely fitted to respective ends of the silica tube and which have an external diameter which is substantially the same as the diameter of the heating roller. The lamp heater is secured by a lamp holder and frame to the shaft of the heat roller. The heat roller is rotatably supported by a bearing and is driven by a driving gear.
