PURPOSE:To efficiently exhaust temperature risen air of the inside of a body by fixing a hollow reinforcing member to a rear frame of a copying machine body, providing a through-hole opened to the inside of the body on this reinforcing member, and also, connecting the reinforcing member and an exhaust fan by an exhaust duct. CONSTITUTION:A hollow reinforcing member 16 fixed to a frame rear part 15a of a body 1, and an exhaust fan 23 are connected by an exhaust duct 18, and air of the inside of the body 1 is exhausted from a through-hole 16b opened to the reinforcing member 16. Accordingly, temperature risen air in the periphery of an apparatus generating a large quantity of heat, such as a fixing device can be exhausted efficiently. In such a way, a temperature rise of the inside of the body 1 can be prevented without using an exhaust fan having a large capacity, therefore, it can be prevented that a photosensitive body, a developing material, a cleaning device, etc., are deteriorated due to heat, and also, it is unnecessary to increase the capacity and the number of pieces of the exhaust fan, therefore, it is not feared that a secondary fault such as a noise, etc., is generated. |
