ABSTRACT:
A cooling apparatus of an electrophotographic image forming apparatus includes a cooling fan and a first opening. The cooling fan emits heat in the electrophotographic image forming apparatus to an outside of the electrophotographic image forming apparatus, is installed in any one of two frames that are opposite to each other so as to support a fusing unit, is disposed in a direction where a paper is discharged from the fusing unit, and allows internal air to flow out. The first opening is formed in a first frame that is opposite to a second frame in which the cooling fan is installed, and allows external air to flow into the electrophotographic image forming apparatus. The cooling apparatus is applied to a dry or wet electrophotographic image forming apparatus. The cooling apparatus emits heat generated from a fusing unit to the outside without affecting temperatures of a photosensitive drum and a developer unit so as to prolong a usable period of the photosensitive drum and improve an image quality. Also, waste toner is not congealed so as to reduce a load exerted on the cooling apparatus and the developer unit.
