Patent ID: 8099034

Claim:
A fixing apparatus having a first roller and a second roller, a biasing portion that presses the first roller and the second roller against each other, and a driving portion that rotates the first roller and the second roller, and that sandwiches a recording material in a nip region between the first roller and the second roller and transports the recording material, the fixing apparatus comprising: a swing cam that rotates in one direction by a rotational driving force provided by the driving portion being transmitted thereto; a displacement support member that axially supports the second roller and displaces the second roller so that the second roller is brought into and out of contact with the first roller; a pressure release cam that slidingly contacts the displacement support member; a one-way clutch that is provided to a shaft of the pressure release cam; and a swing lever that is connected to the one-way clutch and is biased so as to slidingly contact the swing cam, wherein when the swing cam is rotated in one direction due to the rotational driving force provided by the driving portion, the swing lever that slidingly contacts the swing cam repeatedly swings, swinging the swing lever is transmitted via the one-way clutch to the pressure release cam as intermittent rotation in one direction, the pressure release cam pushes away the displacement support member, opposing a biasing force applied by the biasing portion, the displacement support member and the second roller are displaced, and the second roller is separated from the first roller.
