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.
