Abstract
An image forming apparatus includes an image forming unit that creates an image and a liquid cooling unit. The liquid cooling unit includes a heat receiving disposed in contact with a temperature rising portion, in the image forming unit, in which a temperature rises due to an image forming operation by the image forming unit, a heat radiating unit that radiates heat of a cooling liquid, a flow passage forming member that allows the cooling liquid to circulate between the heat receiving unit and the heat radiating unit, and a conveying unit that conveys the cooling liquid through the flow passage forming member. The heat radiating unit includes a radiator, and the radiator is disposed at a downstream side of the conveying unit in a cooling liquid flow direction and at an upstream side of the heat receiving unit in the cooling liquid flow direction.
