摘要： There is provided a fixing device including: a heating member that, while rotating, heats and fixes a developer image onto a recording medium; a pressing member that nips and presses the recording medium between itself and the heating member; an external heating member configured to make contact with an outer surface of the heating member and to move away from the outer surface of the heating member, the external heating member making contact with the outer surface of the heating member and heating the heating member; and a moving section that computes a contact position of a leading edge of the recording medium and the outer surface of the heating member, and moves the external heating member such that the external heating member contacts the outer surface of the heating member based on the computed position.

摘要： A fixing device includes a fixing member, a pressing member, a heating member, a movement mechanism, and a control unit. The fixing member fixes a toner image onto a recording material. The pressing member is 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 heating member heats the outer circumferential surface of the fixing member. The movement mechanism moves the heating member to contact with and be apart from the fixing member. The control unit 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 a 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.
