Abstract
An image forming apparatus includes a fixing unit and an apparatus main body. The fixing unit includes a heating unit, a pressure roller, first and second cam members, and a pressure force release unit. The pressure force release unit switches a position of the heating unit between a first position at which a predetermined pressure force is applied from the pressure roller to a fixing nip portion, and a second position at which the applied predetermined pressure force is reduced or released. The apparatus main body includes first and second doors that are opened and closed and contain the fixing unit. The first cam member rotates with an open and close of the first door, and the second cam member rotates with an open and close of the second door. A rotational center of the second cam member is arranged coaxially with a rotational center of the first cam member.
