A cooling device including at least two cooling members to cool a recording medium passing thereover, a coolant circulation unit to circulate a coolant, and tubing that connects the coolant circulation unit to the cooling members and through which the coolant circulates. Each of the cooling members includes a heat-absorbing surface that directly contacts the recording medium or indirectly contacts the recording medium via a thermal transmission member, an internal channel provided within each of the cooling members through which the coolant circulates, and a channel inlet and outlet formed at downstream and upstream ends of each of the cooling members in a direction of conveyance of the recording medium, respectively. One of an interval and a thermal insulator is provided between the cooling members.

An image forming apparatus having a liquid-cooled cooling system prevents problems caused by a potential leakage of coolant used in the liquid-cooled cooling system. The liquid-cooled cooling system cools a heat-generating image forming portion using the coolant, which is circulated by a pump through a circulating path. The cooling system includes a heat-receiving member disposed in thermal contact with the image forming portion to absorb heat generated by the image forming portion. The heat-receiving member is connected with the circulating path via a joint. The joint is disposed within an enclosed space between the image forming portion and an electrical component drive portion for driving or controlling the image forming portion, so that the image forming portion and the electrical component drive portion can be protected from the coolant in the event of coolant leakage via the joint.

In order to form a circulating route of a liquid cooling medium for cooling a temperature rising part of an image forming apparatus, a liquid-cooling type cooling device includes a heat receiving section which causes the liquid cooling medium to absorb heat of the temperature rising part, a radiator which causes the heat of the liquid cooling medium to release, and a pump which circulates the liquid cooling medium. The heat receiving section includes a heat receiving main body in which a flowing route of the liquid cooling medium and a contacting surface for contacting the temperature rising part are formed, and a heat receiving main body covering part which covers outer surfaces other than the contacting surface of the heat receiving main body. The heat receiving main body covering part is formed of a material whose heat conductivity is lower than that of the heat receiving main body.

A twinax cable includes at least a pair of core wires, each of which includes a conductor and an insulator covering an outer periphery of the conductor. The insulator includes an inner insulator covering the outer periphery of the conductor and an outer insulator covering an outer periphery of the inner insulator. The inner insulator is formed by a non-colored compressed insulator. The outer insulator is formed by a colored compressed insulator. A thickness of the outer insulator is formed thinner than a thickness of the inner insulator. The outer insulators of the pair of core wires are formed to have hues that are set respectively differently.
