ABSTRACT:
The roller has a roller body having a small heat capacity, a bonding layer formed substantially uniformaly on the outer peripheral surface of the roller body, a lower insulating layer provided on the bonding layer; a heat generating layer provided on the lower insulating layer and having a ceramic matrix and a metallic resistance layer constituted by a metal dispersed in the ceramic matrix, the metallic resistance layer extending substantially continuously in the lengthwise direction of the roller, the heat generating layer having a thermal expansion coefficient substantially the same that of the lower insulating layer, an upper insulating layer provided on the heat generating layer, a protective layer formed on the upper insulating layer so as to prevent offset of the toner images, and an electrode layer formed on each end of the roller and adapted to connect the heat generating layer to an external power source.
