摘要： In a fixing device, a pressing member rotates in a predetermined direction of rotation. A flexible fixing member is disposed opposite the pressing member to rotate in accordance with rotation of the pressing member. A nip formation member is provided inside a loop formed by the fixing member and pressed against the pressing member via the fixing member to form a nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. A contact member pressingly contacts an outer circumferential surface of the rotating fixing member at both ends of the fixing member in an axial direction thereof.

摘要： A fixing device includes a fixing member formed into a loop and rotatable in a predetermined direction of rotation. A heating assembly faces a first region on an inner circumferential surface of the fixing member to heat the fixing member. The heating assembly is thermally deformed to contact and move the fixing member. A first fixing member support and a second fixing member support face a second region on the inner circumferential surface of the fixing member other than the first region. The first fixing member support and the second fixing member support contact and support the rotating fixing member moved by the thermally deformed heating assembly.

摘要： A fixing device includes a tubular belt holder, a rotatable flexible fuser belt, a contact member, a pressure member, and a heater. The tubular belt holder extends in an axial direction thereof. The fuser belt is looped into a generally cylindrical configuration around the belt holder. The tubular belt holder retains the fuser belt in shape as the belt rotates in a circumferential direction. The contact member and pressure member extend in the axial direction. The pressure member presses against the contact member through the fuser belt to form a fixing nip. The heater is disposed to heat a predetermined circumferential portion of the fuser belt. The belt holder includes a first circumferential section and a second circumferential section. The first circumferential section faces the heated portion. The second circumferential section faces upstream from the heated portion in the circumferential direction.
