Abstract:
A fixing device has a fixing member, a pressing member, a pressing mechanism, a pressure changing mechanism, and a moving mechanism. The fixing member has a fixing belt. The pressing member forms a fixing nip portion by making contact with the fixing member. The pressing mechanism presses the pressing member against the fixing member to apply a nip pressure to the fixing nip portion. The pressure changing mechanism changes the nip pressure. The moving mechanism moves the fixing member in a sheet width direction which is perpendicular to a sheet conveying direction. The pressing mechanism has a holding member rotatably holding the pressing member and held swingably in such directions as to approach and recede from the fixing member. The moving mechanism moves the fixing member in the sheet width direction in coordination with the nip pressure being applied or removed by the pressure changing mechanism.

Claim (Index 1):
A fixing device comprising:\n a fixing member having an endless fixing belt provided rotatably; a pressing member forming a fixing nip portion by making contact with the fixing member; a pressing mechanism pressing the pressing member against the fixing member to apply a nip pressure to the fixing nip portion; a pressure changing mechanism changing the nip pressure at the fixing nip portion; and a moving mechanism moving the fixing member in a recording medium width direction which is perpendicular to a recording medium conveying direction, the fixing device fixing an unfixed toner image to the recording medium passing through the fixing nip portion, wherein the pressing mechanism includes:\n a holding member which rotatably holds the pressing member and which is held so as to be swingable in such directions as to approach and recede from the fixing member; and \n a first biasing member biasing the holding member in such a direction that the pressing member approaches the fixing member, \n the pressure changing mechanism\n makes the first biasing member generate a biasing force to swing the holding member in a first direction, thereby to apply the nip pressure at the fixing nip portion, and \n removes or reduces the biasing force by the first biasing member to swing the holding member in a second direction opposite to the first direction, thereby to remove the nip pressure, and \n the moving mechanism moves the fixing member in the recording medium width direction in coordination with the nip pressure being applied or removed by the pressure changing mechanism.
