Abstract:
A fixing device includes a fixing rotary body to come into contact with a toner image on a recording medium and a pressing rotary body separably pressed against the fixing rotary body to press the recording medium against the fixing rotary body. A cooler, disposed opposite the pressing rotary body to cool the pressing rotary body, includes a fan to move air to the pressing rotary body and at least one inlet duct interposed between the fan and the pressing rotary body to supply air from the fan to the pressing rotary body. The at least one inlet duct selectively cools the pressing rotary body in a variable axial span in an axial direction thereof.
