Abstract:
To provide a cooling device that can remove an attachment attached to belts that sandwich and convey a recording material due to cooling.SOLUTION: A recording material cooling device 20 comprises: a rotating endless first belt 21; and an endless second belt 25 that forms a cooling nip T4 with the first belt 21, sandwiches a recording material at the cooling nip T4, and rotates to convey the recording material. A heat sink 30 is disposed on the first belt 21 side. The heat sink 30 is in contact with the first belt 21 to cool the first belt 21. Whereas on the second belt 25 side where the heat sink 30 is not disposed, a belt cleaning device 90 is disposed. As the second belt 25 is not cooled by the heat sink 30, an attachment, such as toner and wax can easily attach to the second belt; the belt cleaning device 90 rubs the second belt 25 to remove the attachment attached to the second belt 25.SELECTED DRAWING: Figure 3
