PURPOSE:To arrange a rotational inertial body by constituting the inertial body as a thin one and deviating the attaching position of the inertial body to a shaft in the case of providing the inertial body on each photosensitive drum in a color electrophotographic copying machine constituted by arranging plural photosensitive drums in parallel. CONSTITUTION:A mechanism for forming a color toner image and superposing and transferring it on paper in the same manner as the case of a general color electrophotographic copying machine is arranged on the photosensitive drum 2. As to the drum 2, the rotational inertial body 30 is fixed and arranged on the shaft 20 of the drum 2, and the diameter D of the inertial body 30 is made larger than the diameter of the drum 2, so that the value of angular moment is made large. The inertial body 30 is arranged on the shaft 20 by shifting a phase in a state where a distance from a frame 21 is made different and they do not interfere. |
