Abstract
A press cam is driven when fixing rollers are rotated for a warm-up operation at the time the power is applied simultaneously with the timing a recording material is fed to a fixing roller whereby an oil coating roller is controlled to be brought in contact with and moved away from the fixing rollers. Oil is coated on the fixing rollers for only a predetermined period of time during the fixing rollers are rotated at the warm-up operation which correspond to the time until the recording material reaches the fixing rollers.
