Abstract:
As a projection extending member is arranged adjacently to a projection, a sensor S1 produces an “ON” state output when an eccentric cam starts turning even in non-printing mode. The time from when the eccentric cam starts turning until sensor S1 changes its output from “ON” to “OFF” becomes longer when a new intermediate transfer belt unit is used than when a used intermediate transfer belt unit is used. The length of this time is measured so as to detect whether the intermediate transfer belt unit is brand-new or old.
