ABSTRACT:
A cooling unit is provided to an image forming device. The image forming device includes a process unit having a photosensitive body on which is formed an electrostatic latent image and a developing unit for forming a toner image on the photosensitive body based on the electrostatic latent image; a transfer unit that transfers the toner image onto a sheet; and a fixing unit that thermally fixes the toner image onto the sheet, the process unit and the fixing unit having facing surfaces that face each other. The cooling unit itself includes: an airflow duct disposed between the facing surfaces of the process unit and the fixing unit and formed with at least either process-unit-side holes facing the process unit or fixing-unit-side holes facing the fixing unit; and a cooling fan that draws air from around a corresponding one of the process unit and the fixing unit through the process-unit-side, the fixing-unit-side holes, or both, through the airflow duct, and out of the image forming device.
