PURPOSE:To enhance the quality of image by decreasing speed variation of the rotor of an electrophotographic image output apparatus. CONSTITUTION:A sliding member 18 having a blade 19 consisting of rubber, etc., is contacted with a sensitive drum 2 in its position not related to image formation, and the damping coefficient ratio zeta of the drum is increased so that momentary speed variation can be damped quickly, and the rotating speed is kept constant. Thereby the speed variation of the drum as a rotor is decreased to lead to enhancement of the image quality. |
