摘要:
A fixing device includes a rotatable fixing member, a pressing member, a motor, and an oil applier. The pressing member contacts the fixing member. The oil applier includes an application roller and an oil supply mechanism. The application roller applies oil to one of the fixing member and the pressing member. The oil supply mechanism supplies oil to the application roller. The motor is provided independent of other drivers, and supplies a driving force to the application roller to rotate the application roller at an arbitrary speed.

An image forming apparatus includes an oil input device and a fixing device including a fixing member, a pressing member, and an oil applier. In the oil applier, an oil application member applies oil supplied from an oil supply mechanism to one of the fixing member and the pressing member. In the oil supply mechanism, an oil supply member provided adjacent to an oil storage member supplies oil sent from the oil storage member to the oil application member. When the fixing device is reattached to the image forming apparatus after the fixing device is detached from the image forming apparatus, oil sent from the oil input device through an oil inlet overflows the oil storage member, and is supplied to one of the oil supply member and the oil application member provided adjacent to the oil storage member before an image forming operation starts.

A fixing device includes a fixing member, a pressing member, and an oil applier. In the oil applier, an oil application member applies oil supplied from an oil supply mechanism to one of the fixing member and the pressing member. In the oil supply mechanism, an oil storage member is provided above and adjacent to one of an oil supply member and the oil application member to supply oil overflowing the oil storage member, when oil is put into the oil storage member through an oil inlet, to one of the oil supply member and the oil application member. The oil supply member provided adjacent to the oil storage member supplies oil sent from the oil storage member to the oil application member.

A fixing device includes a rotatable first nip formation member, a rotatable second nip formation member, a first heater, a second heater, and a controller. The second nip formation member is provided under the first nip formation member to contact the first nip formation member to form a fixing nip portion between the first nip formation member and the second nip formation member. The first heater heats the first nip formation member. The second heater heats the second nip formation member. The controller supplies a portion of power to the second heater and the remainder of power to the first heater when a plurality of sheets having a sheet weight not greater than about 100 g/m2 passes through the fixing nip portion continuously.

A fixing device includes a fixing belt looped over a first roller and a second roller and rotatable in a predetermined direction of rotation and a pressure rotator to press against the first roller via the fixing belt to form a fixing nip between the fixing belt and the pressure rotator. A separation aid, disposed downstream from the fixing nip in the direction of rotation of the fixing belt, contacts an inner circumferential surface of the fixing belt to decrease a radius of curvature of the fixing belt. A polishing roller, disposed downstream from the separation aid and upstream from the second roller in the direction of rotation of the fixing belt, contacts an outer circumferential surface of the fixing belt. An opposed roller, disposed opposite the polishing roller via the fixing belt, forms a polishing nip between the polishing roller and the fixing belt.

A sheet separation device includes a separator disposed to contact one face of a sheet conveyed through a nip between conveyors contacting each other. The separator configured to separate from surfaces of the conveyors the sheet conveyed through the nip. The separator includes a conveyance face and a slanted face. The conveyance face is configured to contact and convey the sheet conveyed through the nip. The slanted face is disposed closer to the nip than the conveyance face and inclined with respect to the conveyance face toward one conveyor of the conveyors at a same side as the one face of the sheet.

A fixing device includes an elastic rotator and a cooler disposed opposite the rotator to cool the rotator with cooling air. A mover contacts and moves the rotator to a first position where the rotator is disposed opposite the cooler with an increased first interval therebetween and a second position where the rotator is disposed opposite the cooler with a decreased second interval therebetween. A rectification plate is movably mounted on the cooler to contact the rotator constantly to guide the cooling air to the cooler.

A fixing device includes a fixing belt that is endless and rotatable in a rotation direction and a nip former stretching the fixing belt and including an elastic layer as a surface layer. A pressure rotator presses against the nip former via the fixing belt to form a fixing nip between the fixing belt and the pressure rotator, through which a recording medium is conveyed. A presser is disposed downstream from an exit of the fixing nip in a recording medium conveyance direction. The presser brings the fixing belt into contact with the pressure rotator.

A fixing device includes a first roller contacting a fixing belt to generate a rotation friction force therebetween to rotate the fixing belt and a second roller contacting the fixing belt to exert a first inhibition force to the fixing belt in a direction opposite a direction of rotation of the fixing belt. A separation aid is disposed downstream from a fixing nip formed between the fixing belt and a pressure rotator in the direction of rotation of the fixing belt to decrease a curvature of the fixing belt and exert a second inhibition force to the fixing belt in the direction opposite the direction of rotation of the fixing belt. The second inhibition force is added to the first inhibition force to obtain a combined inhibition force that is smaller than the rotation friction force between the fixing belt and the first roller.
