Abstract
An image forming apparatus includes an apparatus main body having an engagement mechanism and a second opening and further includes a fixing unit having a pressure releasing mechanism. The engagement mechanism includes a first engagement portion. The pressure releasing mechanism includes a first engaged portion engaging with the first engagement portion. In a process in which a first opening/closing member is opened from a closed state, the first engagement portion positioned on a second opening side of the first engaged portion pushes the first engaged portion from the second opening side to reduce or release an urging force applied to a fixing nip portion. In a state where the first opening/closing member is closed, the first engagement portion and the first engaged portion are disengaged, and the first engagement portion is retreated from a path of the first engaged portion when a fixing unit is detached from the second opening.
