| 1. A method for fixing developing agent to an image forming medium, the method comprising:
holding in contact a press roller with a heat roller under pressure and heating by heat coming from the heat roller;
detecting the humidity of ambient air;
storing, in a memory, a warming up time for warming up the heat roller and the press roller, the warming up time being stored
corresponding to the humidity of ambient air such that the higher the humidity of ambient air, the longer the warming up time
becomes; and
defining the warming up time corresponding to the humidity detected by the humidity sensor based on the data stored in the
memory.
