PURPOSE:To enhance the quality of image by decreasing speed variation of the rotor of an electrophotographic image output apparatus. CONSTITUTION:A disc-form inertial member 8 is installed inside of a sensitive drum 2, and the position of this member 8 is made changeable within the sensitive drum 2. Thereby the distribution of the inertial moment of the drum 2 is set any as desire to prevent resonance of the drum 2 which is a rotor and decrease speed variation, which should lead to enhancement of the image quality. |
