摘要： A fixing device includes an endless flexible belt, a stationary pad, a rotary pressure member, and a reinforcing member. The endless flexible belt is looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof. The stationary pad is stationarily disposed inside the loop of the belt. The rotary pressure member is disposed parallel to the belt. The rotary pressure member presses against the stationary pad via the belt to form a nip therebetween. The reinforcing member is stationarily disposed in contact with the stationary pad inside the loop of the belt for reinforcing the stationary pad. The stationary pad includes two or more contact portions spaced apart from each other in the conveyance direction, each generally extending in the axial direction of the looped belt and protruding toward the reinforcing member to contact the reinforcing member.

摘要： A fixing device includes an endless belt rotatable in a predetermined direction of rotation and a nip formation assembly disposed opposite an inner circumferential surface of the endless belt. An opposed rotary body is pressed against the nip formation assembly via the endless belt to form a fixing nip between the endless belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A belt holder contacts and supports each lateral end of the endless belt in an axial direction thereof. The belt holder is isolated from the opposed rotary body with a first interval interposed therebetween in the axial direction of the endless belt.
