1. An image forming apparatus comprising:
a body housing; a paper feeding unit accommodated in the body housing to provide a recording medium; an image forming unit accommodated in the body housing to form an image on the recording medium; a fixing unit accommodated in the body housing to fix the image formed by the image forming unit; and a cooling unit which discharges heat generated in the fixing unit to the outside, the cooling unit comprising:
an inhalation part, a first channel, a second channel, and a discharging part, that are all formed in the body housing, for air to flow,wherein the first channel extending between the inhalation part and the second channel and formed in a straight line adjacently to the fixing unit,wherein the second channel is formed at one end of the first channel and perpendicular to the first channel, and comprises:
a fan, opposite to and facing the inhalation part, to draw air out of the first channel so that an air flow in the second channel is perpendicular to an air flow in the first channel, andan air purification module to generate ions reacting to foreign substances in air that traveled through the first channel and then passed through the fan to purify the air, wherein the fixing unit comprises a heating roller to generate heat, and the first channel is formed to extend in a lengthwise direction of the heating roller adjacently to the heating roller allowing the air to flow in the lengthwise direction of the heating roller, wherein the air purification module comprises a cation generating unit to produce cations and an anion generating unit installed distantly from the cation generating unit in a direction of air traveling to produce anions. |
