Abstract
Disclosed is a fixing device, which makes it possible to prevent the air blasting section from deterioration, caused by heat transferred from the duct to the air blasting section. The fixing device includes a fixing section to fix the toner image onto the paper sheet; a heat source; and a separating section to separate the paper sheet from the pair of fixing members. On the other hand, the separating section includes: a gas blasting section to blast a gas; and a duct to guide the gas towards the pair of fixing members, and that is provided with a duct wall serving as a heat receiving surface to receive radiation heat irradiated from the fixing section, and at least one of the gas blasting section and the duct is provided with such a connection structure that suppresses heat transferring action from the duct to the gas blasting section.
