| 1. An image formation apparatus, comprising:
a first driving source for driving a feed roller and a fixing unit;
a second driving source for driving at least one photo conductor out of a plurality of the photo conductors and a middle transfer
belt;
a third driving source for driving the photo conductors other than the photo conductor driven by the second driving source;
a temperature detecting unit for detecting a temperature of the fixing unit, and for determining whether the temperature is
greater than a predetermined threshold value; and
a control unit for starting the first driving source, the second driving source, and the third driving source in this sequence
if the temperature detecting unit determines that the temperature of the fixing unit is greater than the predetermined threshold
value.
