Abstract
A fixing device includes a fixing member that is heated, a pressure member, a fixed housing, a movable housing, a moving mechanism, a separating member, a regulating portion, and a link member. The link member is interposed between the movable housing and the separating member. In a pressurized state, the separating member turns about a support shaft in a direction where the separating member approaches to the fixing member by its own weight of the separating member. When a fixing pressure is switched from the pressurized state to a reduced pressure state, moving the movable housing in the direction where the movable housing separates from the fixed housing by the moving mechanism causes the separating member to turn about the support shaft via the link member in the direction where the separating member separates from the fixing member and causes the regulating portion to regulate turning of the separating member.
