Patent ID: 7382995

Claim:
A fixing apparatus for fixing an unfixed image on a recording material, comprising: a heating member, having a conductive layer, that is rotatably provided; a pressure member that is rotatably provided and that is brought into press-contact with the heating member, thereby forming a fixing nip part to pass the recording material between the pressure member and the heating member; a heating unit that performs induction heating on the heating member via the conductive layer; a driving unit that rotates the heating member; an attachment/separation unit that attaches or separates the heating member to/from the pressure member; an acquisition unit that acquires information corresponding to a temperature of the heating member; and a controller that drives the heating member by the driving unit and heats the heating member by the heating unit in a state where the heating member and the pressure member are separated by the attachment/separation unit, and that brings the heating member and the pressure member into press-contact by the attachment/separation unit when the information acquired by the acquisition unit satisfies a predetermined condition, wherein the heating member is an endless belt member, the acquisition unit acquires elapsed time from start of heating of the heating member by the heating unit as the information, and the controller brings the heating member and the pressure member into press-contact by the attachment/separation unit when the elapsed time acquired by the acquisition unit is equal to or longer than a predetermined period.
