发明名称 IMAGE FORMING DEVICE HAVING INTERNAL COOLING DEVICE
摘要 PURPOSE:To miniaturize the title device, and also, to prevent a developer from being scattered due to a ventilation by utilizing a thermoelement which has utilized a semiconductor, as a cooling source. CONSTITUTION:An internal temperature detecting means 1 is attached to a part where a temperature detection is necessary, of an image forming device 10, and a control means 2 compares an actual internal temperature which is detected by the internal temperature detecting means 1 with a temperature set in advance and decides whether it is higher or not, and outputs a temperature control signal based on its decision. As for a thermoelement 3, a semiconductor is utilized, and in accordance with a temperature control signal from the control means 2, a cooling process is executed. In such a way, the device is miniaturized, and also, it does not occur that a developer is scattered due to a ventilation.
