摘要： A recording-material cooling device includes a first belt, a first cooling unit, and a second cooling unit. The first belt is disposed at a first face side of a recording material. The first cooling unit has a first heat absorbing surface to contact the first belt to absorb heat of the recording material. The second cooling unit has a second heat absorbing surface to directly or indirectly contact the recording material to absorb heat of the recording material. The second cooling unit is disposed at a second face side of the recording material. The first and second cooling units are offset from each other in a transport direction of the recording material. Each of the first and second surfaces has a shape in which an inner area protrudes beyond opposed ends in the transport direction. The first and second surfaces overlap each other in a direction crossing the transport direction.

摘要： A recording-material cooling device includes a first cooling member, a second cooling member, an approach-and-separation member, and a positioning member. The first cooling member is disposed at a first face side of a recording material to absorb heat of the recording material. The second cooling member is disposed at a second face side of the recording material to absorb heat of the recording material. The approach-and-separation member brings the first cooling member and the second cooling member close to and away from each other. The positioning member positions the first cooling member and the second cooling member relatively brought close to each other by the approach-and-separation member.

摘要： A recording-material cooling device is disposed downstream from a fixing device in a transport direction of a recording material. The fixing device includes a fixing member and a pressing member to fix an unfixed toner image on the recording material. The recording-material cooling device includes a first cooling unit disposed at a same side as the pressing member relative to the recording material, a second cooling unit disposed at a same side as the fixing member relative to the recording material, and a third cooling unit disposed at the same side as the pressing member relative to the recording material. The first cooling unit, the second cooling unit, and the third cooling unit are arranged in an order of the first cooling unit, the second cooling unit, and the third cooling unit from upstream to downstream in the transport direction of the recording material.

摘要： A recording medium conveyor, which is incorporated in an image forming apparatus, includes a first conveyor and a second conveyor disposed facing the first conveyor. The first conveyor and the second conveyor sandwich a recording medium therebetween and convey the recording medium to a downstream side of an image forming apparatus in a recording medium conveying direction. At least one of the first conveyor and the second conveyor includes a belt having an inner circumferential face, and a cooler to cool the recording medium. The cooler has a heat absorbing face that contacts the inner circumferential face of the belt and that has an air flow path formed thereon to expose the inner circumferential face of the belt to open air.
