摘要： A fixing device includes a fixing rotator, a pressure rotator, a cooling assembly, and an air regulation plate. The cooling assembly blows air onto an outer circumferential face of the pressure rotator to cool the outer circumferential face of the pressure rotator. The air regulation plate is disposed opposing the outer circumferential face of the pressure rotator with a clearance between the air regulation plate and the outer circumferential face of the pressure rotator, to regulate a flow direction or amount of one of air to be blown onto the outer circumferential face of the pressure rotator and air having been blown onto the outer circumferential face of the pressure rotator. The air regulation plate has a leading end opposing the outer circumferential face of the pressure rotator. The leading end has a shape following the outer circumferential face of the pressure rotator.

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.

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.
