Abstract
A cooling device includes a heat receiving unit disposed to contact a surface of a temperature-increasing part the temperature of which increases during an image forming process; a radiation unit transferring heat from a cooling liquid; a tube for circulating the cooling liquid between the heat receiving unit and the radiation unit in a liquid circulation direction; a conveying unit conveying the cooling liquid through the tube; a coupling having an internal flow path and including a first end to which a first part of the tube is connected and a second end to which a second part of the tube is connected; and an outlet for draining the cooling liquid from the tube. At least one of the first part of the tube and the second part of the tube extends to a position lower than the position of the coupling.
