    摘要： A sheet suction device includes a drum having multiple suction ports in a circumferential surface of the drum, the drum configured to bear a sheet on the circumferential surface and rotate in a circumferential direction of the drum, and a suction device configured to suck the sheet through the multiple suction ports to attract the sheet on the circumferential surface. The drum includes multiple suction regions aligned in the circumferential direction on the circumferential surface, each of the multiple suction regions includes the multiple suction ports aligned in the circumferential direction and in an axial direction of the drum on the circumferential surface, the multiple suction regions include an upstream region, a middle region, and a downstream region in the circumferential direction, and the middle region has the multiple suction ports at both outer sides in the axial direction of the drum.

    摘要： A cooling device, which is includable to an image forming apparatus, includes a conveyor, a cooler, and at least one roller. The conveyor conveys a recording medium with a first roller and a second roller each of which is in a loop. The cooler is disposed within the loop of the second belt and cools the recording medium discharged from a fixing device. The at least one roller is a roller within the loop of the first belt and between a first end roller disposed at an end of the first belt facing a plane of a conveyance path. Alternatively, the at least one roller is multiple rollers within the loop of the first belt and contacts an inner circumferential surface of the first belt against the cooler and an upstream roller of the multiple rollers has a smallest pressing force of the multiple rollers.

    摘要： Disclosed herein are emissive ceramic elements having low amounts of certain trace elements. Applicants have surprisingly found that a lower internal quantum efficiency (IQE) may be attributed to specific trace elements that, even at very low amounts (e.g., 50 ppm or less), can cause significant deleterious effects on IQE. In some embodiments, the emissive ceramic element includes a garnet host material and an amount of Ce dopant. The emissive ceramic element may, in some embodiments, have an amount of Na in the composition less than about 67 ppm, an amount of Mg in the composition less than about 23 ppm, or an amount of Fe in the composition less than about 21 ppm.
