Abstract
A fixing device includes a fixing belt that is endless and rotatable. A nip formation pad is disposed opposite an inner circumferential face of the fixing belt via a lubricant. A pressure roller sandwiches the fixing belt together with the nip formation pad to form a pressing region through which a recording medium is conveyed. A cap is disposed opposite a lateral end of the fixing belt in an axial direction of the fixing belt. A seal is tubular and contacts an outer circumferential face of the fixing belt in at least a part of an inner circumferential face of the seal. The seal seals a gap between the cap and the fixing belt. The seal includes a non-perpendicular portion that is not perpendicular to a circumferential direction of the fixing belt and defines a slit.
