PURPOSE:To reduce the deterioration of a function, to attain the prolongation of a life, and to reduce the burden of cost on a user by adjusting the function of an ozone-adsorbing filter linking with the time of forming an image and the time of standing by. CONSTITUTION:When the image is formed, a motor 34 is rotated in a fixed direction, and the ozone-adsorbing filter 26 is moved via a worm gear 33 and a rack type gear 32 on a stay 31, and set on a ventilation path 24. At the time of standing-by, the motor 34 is reversely rotated, and the ozone-adsorbing filter 26 is set outside the ventilation path 24. These filter movement control by the motor, is executed by a CPU, with the output of detection by a filler 35, and position sensors 36A and 36B. |
