Abstract
A fixing device includes a fixing belt and a pressure rotator that presses against a nip formation pad via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt. A first holder holds a first lateral end of the fixing belt in an axial direction thereof. A second holder holds a second lateral end of the fixing belt in the axial direction thereof. The second holder, together with the first holder, defines a holder interval provided between the first holder and the second holder in the axial direction of the fixing belt. A lubricant supplying sheet impregnated with a lubricant is sandwiched between the nip formation pad and the fixing belt at the fixing nip. The lubricant supplying sheet has a sheet span in the axial direction of the fixing belt. The sheet span is within the holder interval.
