Abstract: A heating apparatus of the present invention includes a press member that undergoes driven rotation by contacting a heating member that rotates, the press member conveying a recording medium while nipping the recording medium between the press member and the heating member; a contact and separation mechanism that contacts the press member against the heating member and separates the press member away from the heating member; and a drive mechanism that rotationally drives the press member when the press member is separated from the heating member by the contact and separation mechanism.

Abstract: An image formation device is provided, at which a fixing apparatus is disposed inside a housing of a printer main body, and which is configured in a fanless ventilation structure. This image formation device is provided with: a fixing unit mounting portion positioned at an upper portion of the housing, and surrounded by a partition wall and a heat-shielding member extending from a side face of the partition wall, the fixing apparatus being placed on the heat-shielding member, and the fixing unit mounting portion being isolated such that hot air will not flow to equipment inside the housing; a cover member for covering the fixing unit mounting portion; a ventilation portion which includes ventilation apertures formed through the cover member; and a conveyance portion for the recording medium.

Abstract: An apparatus is provided to easily prevent walking of a belt while avoiding twisting, warping and buckling of the belt including using an inexpensive endless belt with low rigidity in a fixation apparatus of so-called belt nip method. The apparatus includes a heating roll, an endless belt that presses against the heating roll and rotates along with the heating roll, and a pressing member that presses the endless belt against the heating roll 1 and forms a contact nip region between the endless belt and the heating roll. A belt walk guide that limits walking of the edge of the endless belt is provided on at least one side of the contact nip region between the between the heating roll and the endless belt. The belt walk guide is positioned on an axis parallel to an axis of the heating roll and passing through the contact nip region. The apparatus also includes a pressure roll and the endless belt.
