摘要： A fixing device includes a guide disposed downstream from a fixing nip formed between a fixing rotator and a pressure rotator, through which a recording medium is conveyed. A pressure rotator side separator, disposed downstream from the fixing nip in a recording medium conveyance direction, includes an opposed tip disposed opposite an outer circumferential surface of the pressure rotator and a separation-conveyance face that separates the recording medium from the pressure rotator. The opposed tip and the separation-conveyance face define a hypothetical circle having a curvature not smaller than 1/20 that intersects a guide face of the guide at an intersection at which a hypothetical tangent is tangent to the hypothetical circle. The hypothetical tangent and the guide face define a downstream intersection angle that is downstream from the hypothetical tangent in the recording medium conveyance direction and is greater than 90 degrees.

摘要： 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.

摘要： 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.

摘要： A fixing device includes a heating roller, a fixing roller, an endless fixing belt, a pressure roller, a temperature gauge, and a cooling device. The fixing belt is stretched between the heating roller and the fixing roller. The pressure roller includes a core rod and an elastic layer formed on an outer circumferential surface of the core rod, and is pressed against the fixing roller via the fixing belt to form a nip portion to thermally fix an image on a recording medium passed through the nip portion. The temperature gauge measures the surface temperature of the pressure roller. The cooling device includes plural cooling units arranged parallel to a rotation axis of the pressure roller, and cools the pressure roller while adjusting the amount of cooling for each of the cooling units in accordance with the surface temperature of the pressure roller measured by the temperature gauge.
