An image forming apparatus of the present invention includes a thermal fixing unit and is capable of varying a sheet conveying speed. The sheet conveying speed is varied in accordance with a resolution selected. The target fixing temperature of the fixing unit is variable in accordance with the sheet conveying speed. Further, the stand-by temperature of the fixing unit after image formation is set in accordance with the resolution selected to thereby control a temperature. This successfully reduces the operator's waiting time and applies adequate heat to a sheet.
