Claims

[Claims for Utility Model Registration] 1. A printing mechanism in which a photoreceptor, in which at least a discharger, an exposure device, and a developer are disposed facing each other, is located on a paper conveyance path is built into the main body housing, and the printing mechanism is operated within the main body housing. In an electrophotographic apparatus in which a cooled part that generates heat is located, a ventilation mechanism is provided that communicates with the outer surface of the main body housing and is connected to the discharger and one of the cooled parts, and the ventilation mechanism is connected to the discharger. 1. An electrophotographic apparatus comprising: time-sharing ventilation means for switching the ventilation direction to either the discharger or the cooled section in conjunction with whether or not the discharger is operated. 2. An electrophotographic apparatus in which a printing mechanism in which a photoreceptor, in which at least a toner cleaner, a discharger, an exposure device, and a developer are disposed facing each other, is located on a paper conveyance path is built into a main body housing, and the printing mechanism is connected to an outer surface of the main body housing. A ventilation mechanism connected to the discharger and the toner cleaner is provided, and the ventilation mechanism switches the ventilation direction to one of the discharger and the toner cleaner depending on whether or not the discharger is activated. An electrophotographic device characterized by being provided with means. 3. In an electrophotographic apparatus in which a printing mechanism in which a photoreceptor in which at least a discharger, an exposure device, and a developer are disposed facing each other is located on a paper conveyance path is built into the main body housing, the discharger communicates with the outer surface of the main body housing. and the developing device, and the ventilation mechanism is provided with a time-sharing ventilation means for switching the ventilation direction to either the discharge device or the developing device in conjunction with whether or not the discharge device is activated. An electrophotographic device characterized by:
