Method and apparatus for image forming capable of effectively performing an image fixing process

A fixing apparatus includes a fixing roller, a heat roller, a seamless fixing belt, a pressure roller, a supporting roller, and a pressure applying member. The heat roller includes a fixing heat source. The seamless fixing belt is extended between the fixing roller and the heat roller. The pressure roller pushes the fixing roller via the fixing belt to form a second fixing-process area. The supporting roller contacts inside the fixing belt and winds the fixing belt around a surface of the pressure roller to form a first fixing-process area upstream of and next to the second fixing-process area. The pressure applying member applies a pressure to the heat roller in a direction opposite to an ejection of the recording sheet from the second fixing-process area to adjust a fixing pressure of the first fixing-process area.
