Abstract:
1. A fixing device comprising: a fixing member that fixes a toner image onto a recording material; a pressing member pressed against an outer circumferential surface of the fixing member to form a fixing pressure part between the pressing member and the fixing member, the fixing pressure part being a part through which a recording material that has an unfixed toner image held thereon passes; a heating member that heats the outer circumferential surface of the fixing member; a movement mechanism which moves the heating member to contact with and be apart from the fixing member; and a control unit which controls the movement mechanism to move the heating member relatively apart from the fixing member after a predetermined time elapses after a trailing end of the recording material in a transport direction thereof passes through the fixing pressure part each time when a recording material passes through the fixing pressure part, wherein each time a recording material passes through the fixing pressure part, the control unit controls the movement mechanism to move the heating member into contact with the fixing member after a predetermined time elapses after a leading end of the recording material in the transport direction thereof enters the fixing pressure part.
