ABSTRACT:
A cooling apparatus and an image forming device having the cooling apparatus are provided. The cooling apparatus includes an induction opening formed at an outer frame to draw the air into the image forming device, an air duct disposed adjacent to a fixing roller in a longitudinal direction thereof, the fixing roller being heated by a heating source therein, and a blower disposed between the induction opening and the air duct to send the air into the air duct from the induction opening. The cooling apparatus moves the air longitudinally along a jam cover disposed adjacent to the fixing roller, and discharges it to the outside. Accordingly, temperatures in the image forming device and of the components therein can be prevented from overheating and being abnormally increased due to a heat emitted from the heating source. As a result, it is possible not only to prevent a performance of the image forming device from deteriorating due to the abnormal increase in the temperatures in the image forming device and of components therein, but also to prevent a user from getting burned due to the jam cover heated by the heat from the heating source during a jam removing.
