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： An image forming apparatus includes a cooling conveyor to cool a recording material having an image fixed by heat while sandwiching and conveying the recording material. The cooling conveyor includes a conveyance belt, a cooling member, and a cooling unit. The conveyance belt sandwiches and conveys the recording material. The cooling member absorbs heat of the recording material via the conveyance belt. The cooling unit maintains the cooling member at low temperature. The cooling conveyor performs control of stopping the cooling unit in a standby state of the image forming apparatus, activating the cooling unit and performing a preliminary cooling operation to decrease temperature of the cooling member after a shift from the standby state to image forming operation, and then bringing the recording material into contact with the conveyance belt.

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 cooling device includes a cooling member to cool a recording material. The cooling member includes a cooling surface member, a heat exchanging member, and a fastening member. The cooling surface member has a cooling surface to directly or indirectly contact the recording material and absorb heat of the recording material to cool the recording material. The heat exchanging member is directly or indirectly joined to the cooling surface member to radiate heat absorbed by the cooling surface member directly or indirectly via a radiation member. The fastening member fastens the cooling surface member and the heat exchanging member to retain a joined state in which the cooling surface member and the heat exchanging member are directly or indirectly joined to each other. The cooling surface member and the heat exchanging member are separable from the joined state to a separated state without damaging the fastening member.
