Cooling device for image forming apparatus

A cooling assembly for an image forming apparatus comprising:

• a case that houses a plurality of heat generating mechanisms, wherein the heat generating mechanisms disposed in the case include
• a processing unit having at least a photosensitive body on which an electrostatic latent image is formed and a developing device for forming a toner image on the photosensitive body,
• an exposure unit that forms the electrostatic latent image on the photosensitive body,
• a fixing unit for heat-fixing the toner image after the image is transferred onto paper,
• a drive motor that drives the processing unit, the exposure unit and the fixing unit, and
• a power source;
• a cooling fan that generates cooling air;
• and
• a plurality of air passages that extend adjacent to the plurality of heat generating mechanisms and channel cooling air from the cooling fan to the plurality of heat generating mechanisms, wherein the plurality of air passages include an air passage for the drive motor, an air passage for the power source and an air passage for the fixing unit, and
• wherein an air blowing direction of the cooling fan is at a non-zero angle with respect to a horizontal plane so that the cooling air generated by the cooling fan advances toward each of the plurality of air passages.

A cooling device for an image forming apparatus comprising:

• a main frame and a main cover attached to thereto, the main frame having an upper portion and a lower portion and the main cover having an air inlet port and an air outlet port;
• an image processing unit disposed in the main frame for forming an image to be developed for printing;
• a fixing unit disposed in the main frame for heat-fixing the image onto a recording medium;
• a cooling fan;
• a drive unit for driving the image processing unit, fixing unit and the cooling fan;
• and
• a power source for powering the drive unit,
• wherein one side of the lower portion of the main frame includes a receptacle portion formed therein that accommodates the cooling fan and has a plurality of air passages formed therein communicating with the cooling fan receptacle to pass cooling air to the image processing unit, fixing unit, drive unit and power source.
