摘要： The present invention provides a fixing device and a digital photocopier which can shorten the time from an instruction of starting image formation to end of fixing. The fixing device is provided in a cylinder made of metal and having a small thickness, and includes a magnetic excitation coil. When the power source is turned on, all the electric power defined by subtracting an electric power amount consumed by components other than the fixing device is supplied to the magnetic excitation coil to perform heating. As the structural components of the photocopier and auxiliary devices added to the photocopier operate, the electric power defined by subtracting, from the maximum input electric power, the electric power consumed by the structural components of the photocopier and the auxiliary devices is supplied to perform heating. In this manner, the heat roller of the fixing device is heated, in a short time, to a temperature which enables fixing, so that the time required for first copying can be shortened.
摘要翻译：本发明提供了一种定影装置和数字复印机，其可以缩短从开始图像形成到结束结束的指令的时间。定影装置设置在由金属制成并具有小厚度的圆筒中，并且包括磁激励线圈。当电源接通时，通过减去除了定影装置以外的部件消耗的电力量而定义的所有电力被提供给磁性励磁线圈进行加热。由于复印机和辅助设备的结构部件添加到复印机中，所以通过从最大输入电力中减去由复印机和辅助设备的结构部件消耗的电力而定义的电力被供给以进行加热。以这种方式，定影装置的加热辊在短时间内被加热到能够进行定影的温度，从而可以缩短第一次复印所需的时间。

摘要： A high-frequency current is supplied from a high-frequency generating circuit to a coil of a heat roller, and a high-frequency magnetic field is generated from the coil. The high-frequency magnetic field causes an eddy current to be generated in the heat roller, and a developer image on a recording medium is fixed by self-generation of heat of the heating roller based on an eddy-current loss. Electric wires between the high-frequency generating circuit and the coil are electrically shielded by a shield member.

摘要： Time data required for an exposing lamp to reach to a standby temperature value from the starting of the exposing lamp heater with a rated current, and time data required for a heat roller to reach to the standby temperature from the starting of the heater lamp of the fixing apparatus with a rated current are retained in a ROM. The temperature of the heat roller and of the exposing lamp is detected when the power-save mode releasing has been instructed by the key. The start beginning timing of the exposing lamp heater and of the heater lamp is controlled so that the temperature of the exposing lamp and of the heat roller may become a standby state at substantially the same time from the time data retained based on the detected temperature value.

摘要： When printing is effected on an obverse surface C1 of a copying paper sheet C, a scan position of a laser beam B on a photosensitive drum 20 is shifted by a first set amount in an axial direction of the photosensitive drum relative to a predetermined reference position. The first set amount corresponds to a positional displacement amount L1 of the copying paper sheet C, which occurs when the copying paper sheet C is first fed to the photosensitive drum 20. In addition, when printing is effected on a reverse, surface C2 of a copying paper sheet C, a scan position of the laser beam B on the photosensitive drum 20 is shifted by a second set amount in the axial direction of the photosensitive drum relative to a predetermined reference position. The second set amount corresponds to a positional displacement amount L2 of the copying paper sheet C, which occurs when the copying paper sheet C, the printing on the obverse surface of which has been finished, is fed once again to the photosensitive drum 20.
摘要翻译：当在复印纸C的正面C1上进行打印时，感光鼓20上的激光束B的扫描位置相对于感光鼓的轴向相对于预定的参考位置偏移第一设定量。第一设定量对应于当复印纸张C首先被供给到感光鼓20时发生的复印纸张C的位置偏移量L1。另外，当在相反的方向进行打印时，复印纸张C，感光鼓20上的激光束B的扫描位置相对于预定的基准位置在感光鼓的轴向方向上偏移第二设定量。第二设定量对应于复印纸C的位置偏移量L2，当复印纸C正面已经完成的印刷纸C被再次送到感光鼓20时发生。
