摘要： PROBLEM TO BE SOLVED: To achieve energy saving by imparting a heat quantity only necessary for fixing a toner image to a transfer material but not imparting an excessive unnecessary heat quantity.SOLUTION: In an image forming apparatus, after starting to blow air with waste heat by a waste heat suction unit 14, a waste heat duct 15 and a waste heat discharge unit 16 to a transfer sheet S prior to transferring an image, the preheated state of the transfer sheet S prior to transferring an image is determined and the heat quantity to be generated by a fixing unit 10 is controlled in such a manner that the heat quantity for fixing a toner image onto the transfer sheet S is a fixing heat quantity necessary for fixing the image in accordance with the preheated state. For example, the time period of blowing air with waste heat is measured, and the preheated state is determined by the measured time period. If preheating of the transfer sheet S before transferring is determined as sufficient in accordance with the preheated state, the heat quantity to be generated by the fixing unit 10 is controlled to a heat quantity calculated by subtracting a predetermined target heat quantity before fixing from the fixing heat quantity.
摘要翻译：要解决的问题：通过赋予仅将转印材料固定调色剂图像所必需的热量而不产生过量的不必要的热量来实现节能。解决方案：在图像形成装置中，在传送图像之前，通过废热抽吸单元14，废热管道15和废热放出单元16开始将废热的空气吹送到转印纸S之后，确定在转印图像之前的转印纸S的预热状态，并且由定影单元10产生的热量被控制成使得将调色剂图像定影到转印纸S上的热量是固定根据预热状态固定图像所需的热量。例如，测量用废热吹送空气的时间段，并且通过测量的时间段确定预热状态。如果根据预热状态将转印片S预热确定为足够，则由定影单元10产生的热量被控制为通过从固定中减去固定前的预定目标热量而计算出的热量热量。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To enable to continue work without stopping a machine even if a carrying passage is not switchable to make it impossible to discharge following paper by the switching of the carrying passage. SOLUTION: During the use of one paper carrying passage for carrying paper when a failure occurs in the paper carrying passage or a discharge destination via the paper carrying passage (S2), the presence or absence of a discharge destination switchable with the discharge destination is confirmed (S5). In the case that the switchable discharge destination exists, the paper is discharged to the discharge destination with the discharge destination switched (S9, S10). In the case that the discharge destination does not exist, the destination is switched to and the paper is discharged to an invalid-paper discharge tray which is prepared for the case that the switchable discharge destination does not exist (S11, S14). Thus, the image forming device can continue image formation without interruption. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve such problems that though a method for preventing image degradation such as color bleeding due to misalignment of superposed images upon forming a multicolor image is carried out by forming a toner image in a line pattern of each color on an image carrying body, detecting the misalignment of toner images by a detecting means and correcting the misalignment, however, the position of a line pattern is erroneously detected when the base density of the image carrying body varies much, which means correction of the base density is important, and that velocity irregularity of the image carrying body induces erroneous detection of the position. SOLUTION: When the unit of an image carrying body is completed, the base density irregularity or velocity irregularity of the image carrying body are measured and memorized as an initial data in a memory means. When a toner image of a line pattern is to be detected, data correction is executed to eliminate the irregularity. In a practical use state, the varying state of the base density with time is monitored every predetermined period to update the memorized data. When the unit or the like is to be exchanged, the corresponding initial data is updated. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：解决这样的问题：为了解决这样的问题，虽然通过以各种颜色的线条图案形成调色剂图像，但是通过在形成多色图像时防止由于叠加图像的未对准而导致的图像劣化的方法进行在图像载体上，通过检测装置检测调色剂图像的未对准并校正未对准，然而，当图像承载体的基本密度变化很大时，错误地检测到线图案的位置，这意味着校正基底密度是重要的，并且图像载体的速度不规则性导致位置的错误检测。解决方案：当图像承载体的单元完成时，图像承载体的基本浓度不规则或速度不规则性被测量并存储在存储装置中作为初始数据。当要检测线图案的调色剂图像时，执行数据校正以消除不规则。在实际使用状态下，每隔规定期间监视基准密度随时间的变化状态，以更新存储的数据。当要交换单元等时，更新相应的初始数据。版权所有（C）2006，JPO＆NCIPI
