<P>PROBLEM TO BE SOLVED: To set a driving voltage for a fan to a minimum required value. <P>SOLUTION: Transition to S112 is performed when it is determined that the fan 401 is rotated in S105 in an image forming apparatus. Next, a driving start voltage Vs for the fan 401 is set (S112). A reference is made to Fig.7. Transition to S113 is performed when it is determined that the fan 401 is not rotated in S108. Next, a driving sustain voltage Vk for the fan 401 is set (S113). A reference is made to Fig.8. <P>COPYRIGHT: (C)2010,JPO&INPIT |
