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.
