图像形成装置、供纸机构劣化判定方法及记录介质
摘要：
本发明提供一种图像形成装置、供纸机构劣化判定方法及记录介质。即便在片材供给时发生了连带输送的情况下也能够准确地判定供纸机构的磨损劣化。图像形成装置(1)具备：速度测定部(51)，测定通过供纸机构(2a)供给的片材的输送速度；连带输送判定部(52)，判定通过速度测定部(51)测定的输送速度是否受到了接下来被供给的片材的影响；校正部(53)，在通过连带输送判定部(52)判定为是受到了接下来被供给的片材的影响的输送速度的情况下，对通过速度测定部(51)测定的输送速度进行校正；以及磨损检测部(54)，基于通过速度测定部(51)测定的输送速度或通过校正部(53)校正后的输送速度，检测供纸机构(2a)的磨损状态。
摘要（英）：

An image forming device comprising: a tray in which multiple number of sheets are stored; a feeder that feeds the sheet stored in the tray; and a hardware processor that: measures a carrying speed of the sheet fed by the feeder; determines whether or not the measured carrying speed is affected by the following sheet; corrects the carrying speed upon determining the carrying speed is affected by the following sheet; and detects a wear status on the feeder based on the measured carrying speed or the corrected carrying speed.
