摘要: 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.

摘要: A fixing device includes a rotatable endless fixing belt, a pressure rotator, a nip formation pad, a lubricant impregnated member, and restrictors. The pressure rotator contacts an outer circumferential face of the fixing belt. The nip formation pad is disposed at an inner circumferential side of the fixing belt, to contact the pressure rotator via the fixing belt to form a nip. The lubricant impregnated member is disposed on the nip formation pad to contact an inner circumferential face of the fixing belt. The lubricant impregnated member is impregnated with lubricant. The restrictors, each disposed at an inner side than each end in a width direction of the fixing belt, regulate movement of the lubricant adhering to the fixing belt, toward each end of the fixing belt in the width direction. The restrictors have a lower absorbability of the lubricant than an absorbability of the lubricant impregnated member.

摘要: A fixing device includes a first rotator and a second rotator pressed against the first rotator to form a fixing nip therebetween, through which a recording medium bearing a toner image is conveyed. A thermal insulation cover is disposed opposite the second rotator. A mover is connected to the second rotator to move the second rotator with respect to the first rotator. The mover is coupled with the thermal insulation cover to move the thermal insulation cover while retaining a predetermined interval between the thermal insulation cover and the second rotator.

摘要: An image forming apparatus includes an image forming device to transfer an image to a recording sheet; a fixing device to feed the recording sheet and fix the image onto the recording sheet; a branching device to switch between an ejection path to eject the recording sheet fed downstream of the fixing device, to outside the apparatus, and a reversing path for duplex printing; and a back curl correction structure disposed in a sheet feeding path between the fixing device and the branching device. The back curl correction structure includes a drive roller; a driven roller; an auxiliary nip portion; a guide member; and a guide moving device to move the guide member to a first position and a second position depending on the condition of the recording sheet.

摘要: A fixing device includes a fixing member; a heater to heat the fixing member; a nip forming member to contact the fixing member; and a pressure member, disposed opposite the nip forming member to press against the fixing member to form a fixing nip portion together with the nip forming member. The fixing device applies heat and pressure to fix an image transferred to a recording sheet when the recording sheet passes through the fixing nip. The nip forming member includes a first and second planar portions disposed at an upstream end and a downstream end, respectively, of the fixing nip portion, and the first planar portion and the second planar portion are continuous with a curved portion of the nip forming member. A guide member guides the recording sheet to bend in a direction opposite a back curl of the recording sheet generated in the fixing nip portion.
