Abstract:
A heat roller device, comprising a heat roller and a press roller positioned opposite said heat roller, for heating an article passed between the two rollers, wherein said heat roller includes a generally cylindrical base material and two heat generating resistances formed on said cylindrical base material, each of said two heat generating resistance generating heat independently of one another, further including a common electrode for supplying current to said two heat generating resistances and separately arranged additional supply electrodes, and control means for separately turning on and off both of said two heat generating resistances as a function of the width of the article and the surface temperature of the heat roller in a manner varying the net heating power supplied to each of the two heat generating resistances and the ratio of the net heating power supplied to one of the two heat generating resistances relative to the net heating power supplied to the other of the two heat generating resistances.
