Abstract
A fixing device includes a heat roller, which is rotatably mounted to a frame, a press roller, which is rotatably mounted to the frame, and a press mechanism for pressing the press roller against the heat roller. The press mechanism has a displacement member that is displaceable in a press direction, a bearing portion that is movable in the opposite direction relative to the displacement member and supports the press roller at a shaft portion thereof, an urging member for urging the bearing portion in the press direction, and displacing structure for displacing the displacement member between a first position corresponding to a non-press position and a second position corresponding to a press position. The urging force of the urging member in the press direction is reinforced by action of the bearing portion, which is displaced in the opposite direction relative to the displacement member when the displacement member is displaced from the first position to the second position.
