Fixation roll of copying machine

Abstract

Abstract PURPOSE:To raise mechanical strength of the main body of a roll and to shorten its warm-up time, by laminating a thin metal layer around cylindrical ceramics to form the main body, and arranging an induction coil in the inside of the main body concentrically. CONSTITUTION:The thin metal layer 2 is formed around the surface of the thin cylindrical ceramics by subjecting a metal, such as Al or Ni, to burning coating treatment, or the like, thus forming the main body 3 of the roll consisting of the ceramics 1 and the layer 2. The induction coil 4 is concentrically arranged in the main body 3 of the roll, and thickness of the burning coating is, e.g., controlled to not above 100mum. As a result, the thickness of the main body 3 is increased with the ceramics 1 to ensure the mechanical strength of the main body 3, and further, thins the layer 2 to enable shortening of the warm-up time.
