If, in a standby state, no operation is executed for a control panel ( 11 ) or ADF ( 13 ) before the elapse of a predetermined time measured by a timer ( 12 ), the set temperature of a fixer ( 20 ) is reduced. After that, if an operation of for the control panel ( 11 ) or ADF ( 13 ) is executed, the set temperature of the fixer ( 20 ) is raised. The set temperature at this time is higher than the fixing temperature in the normal standby state. When the set temperature of the fixer ( 20 ) is set to be higher than that in the normal standby state to temporarily increase the heat amount of the fixer ( 20 ), the heat amount is hardly absorbed by transfer paper sheets at the time of copy. In addition, since the fixing power increases, the time until a fixing set temperature is obtained can be shortened. Accordingly, power consumption can be reduced without any decrease in operability, productivity, and copy quality.
