If the fixing unit temperature is not 50°C or less, the pre-multiple-rotation sequence is performed at 100°C with Dhalf. If Dhalf is unnecessary and the apparatus has a state of JAM return or the like, a JAM wait sequence is performed, whereas if not, it is determined whether a toner empty state by T/D ratio decrease has occurred or not. In a case where the toner empty state has occurred, a return wait sequence is performed. In a case where the toner empty state has not occurred, a door opening/closing wait sequence is performed.  <P>COPYRIGHT: (C)2004,JPO
