PURPOSE:To surely, usefully and efficiently control humidity in respective parts requiring the dehumidification in an electrophotographic process by a few dehumidifying means dehumidifying the inside of a device and to stabilize image quality by surely distributing and sending dehumidified air from the dehumidifying means to the respective parts by an air distributing and sending means. CONSTITUTION:The low-temperature dehumidified air 431 and the heated dehumidified air 432 corresponding to each element in the electrophotographic process are distributively sent to each element, and exhausted from the vicinity of each element. The environment of each element is set according to the conditions of the air 431 and the air 432 and the optimum characteristic of the electrophotographic process is obtained. Therefore, not only a start signal but also output from an outside temperature sensor 300 and other input are inputted in a CPU 500. Then, an operation signal for respective drivers 501 to 503 driving the Peltier element 403 and fans 409 and 410 of the dehumidifying means 400 and other output are fetched from the CPU 500. |
