ABSTRACT:
In a fixing device with a fixing roller that fixes the toner held on a sheet, a pressuring roller that contacts with the fixing roller, and a supply roller that applies the oil to the fixing roller, image noises and offset phenomenon are prevented by replenishing the consumed oil immediately to the supply roller only when the fixing roller is rotating, based on the oil replenishing speed determined by the rotational speed of the fixing roller and the oil replenishing amount determined by the total rotation time of the fixing roller.
