Method of controlling fixing temperature of powder image in electrophotographic copying machine |
摘要 |
A method of controlling the fixing temperature of a powder image comprises the steps of detecting electric power, which is supplied from a power source to a heating element that is contained in a powder image fixing unit to heat the image, by means of a power detector, and controlling the power supplied to the heating element in accordance with an output signal from the detector, thus preventing a variation in the fixing temperature which might result from a fluctuation in the source voltage.
