Fixing device for image forming apparatus

摘要

A device for fixing a toner image on an image forming medium in an image forming apparatus includes a heating roller and a supporting roller for supporting the sheet of paper and transporting the paper, the heating roller having an inner peripheral surface, and at least one electrically resistive layer on the inner surface of the heating roller for fixing the toner image on the paper and reducing heat loss from the heating roller. Further, the device includes a pair of electrodes at opposite ends of the resistive layer for transmitting electrical power to the resistive layer.
