COOLING DEVICE AND IMAGE FORMING APPARATUS

摘要

A cooling device includes a cooling member including a circulation passage for liquid coolant, and a cooling surface being directly or indirectly made to contact with a recording material being conveyed to cool the recording material. The circulation passage includes multiple passage sections arranged crossing to a conveying direction of the recording material, and a folded passage section to guide the liquid coolant from one of the multiple passage sections to another one of the multiple passage sections while changing a flowing direction of the liquid coolant. The folded passage section is disposed outside of an image forming area of the recording material on the cooling surface of the cooling member.
