    • While a recording sheet is passing through a fixing nip formed between a heating roller 41 having a heating layer and a pressing roller 42 pressed against the roller 41, a coil 43 is exited by high-frequency power from a power source and causes the layer to generate heat. An unfixed image on the recording sheet is fixed by the heat. The power source detects a zero cross timing of a rectified alternating current, detects an instantaneous value at a point a predetermined period after the zero cross timing, calculates an effective power of the alternating current based on the instantaneous value, and controls the output power to be a desired value determined based on the effective power and the surface temperature of the roller 41. Thus power input to the power source can be quickly detected and power output to the coil can be quickly and stably controlled.
    • 当记录片材通过形成在具有加热层的加热辊41和压靠在辊41上的加压辊42之间的定影辊隙时,线圈43通过来自电源的高频电力而退出, 发热。 记录纸上的未固定图像由热量固定。 电源检测整流交流电的零交叉定时,在零交叉定时之后的预定时间段检测瞬时值,基于瞬时值计算交流电的有效功率,并将输出功率控制为 是基于辊41的有效功率和表面温度确定的期望值。因此,可以快速检测到电源的输入功率,并且能够快速且稳定地控制对线圈的功率输出。

    • A multi-functional copying machine according to the invention has a scanner for reading the image of a document and image information appended to the document and a printer for forming the image on a medium. It compares the image read by the scanner and the image information, determines according to the extent of alteration of the image whether or not reproduction of the image of the document as it is can be permitted and, if permitted, produces a copy from the reproduced image of the document. If reproduction is forbidden of the image of the document as it is, whether or not to permit restoration of the scanner-read image according to the image information is determined and, if permitted, a copy is produced from the restored image. This makes it possible to keep track of any alteration in a copyrighted image by quick processing, prevent altered copyrighted images from circulation, and protect copyrighted images appropriately.
