Abstract
An image forming apparatus includes an image forming unit including an image carrier and a development device, a transfer unit to transfer an image formed on the image carrier onto a sheet, a fixing device to fix the image on the sheet, a sheet transport unit, a sheet stack portion, an air duct, and a first liquid-cooling device. The first liquid-cooling device includes a first heat receiving member disposed in thermal contact with a first heated portion, a first heat releaser, a first circulation pipe connecting the first heat receiving member and the first heat releaser to circulate a coolant therebetween, a first transport member to transport the coolant through the first circulation pipe, and an airflow generator to generate an airflow with external air to cool the first heat releaser. The air duct guides the air taken in by the airflow generator to a second heated portion.
