  • Patent number: 8412068
    Abstract: A cooling device is disclosed. The cooling device includes a cooling section which is moveably provided with respect to an image forming device body between a first location and a second location, the second location being different from the first location, and which cools surroundings with a cooling medium to be supplied; a cooling medium supply section which is provided at the image forming device body and which cools the cooling medium to supply the cooled cooling medium to the cooling section; and a connecting member which connects the cooling section and the cooling medium supply section to circulate the cooling medium between the cooling section and the cooling medium supply section, wherein the connecting member includes a flexible member and is supported by a guiding member which guides an operation of tracking the connecting member in conjunction with movement of the cooling section.
