1. An image forming apparatus comprising:

  • a main body defining an external appearance of the image forming apparatus;

    a developing unit to form a visible image on a printing medium using developer;

    a fixing device to fix the developer image to the printing medium;

    a heat plate having a first portion placed between the developing unit and the fixing device to absorb heat and a second portion to discharge the heat having an end disposed further from the fixing device than the developing unit such that the end extends away from the fixing device and the developing unit, the first portion of the heat plate includes a shield section located between the developing unit and the fixing device, and the second portion of the heat plate includes a radiator section integrally extending from the shield section, the radiator section being cooled via heat exchange with air; and

    a blowing device to allow the radiator section to be cooled in contact with air,wherein the blowing device includes a blowing fan, a suction duct having a width equivalent to a width of the developing unit, into which air is suctioned from the developing unit, a connection duct to connect the suction duct and the blowing fan to each other, and a discharge duct to guide the air discharged from the blowing fan to an outside of the main body.
