PURPOSE: To prevent the generation of an electrifying noise by making an image carrier by the use of solid resin and providing a damper which absorbs the vibration of an electrifying means, and to prevent soiling of the electrifying means and the image carrier by separating them.
CONSTITUTION: In order to prevent the generation of electrifying noises which result from the vibrations of the image carrier 2-1 and the electrification roller 2-50, the image carrier 2-1 is made of a solid material, so that the same effect as in the case where a vibration-proof material of the maximum width is attached to the inside of a hollow image carrier is obtained and the mass is also increased. A dynamic damper 2-52 is disposed on an electrification roller cover 2-51; thereby, when an image forming device is actuated, the damper receives the vibration of the electrification roller 2-50 via the electrification roller cover 2-51 and vibrates together. Since, in a system, the dynamic damper 2-52 is more vibratile than the electrification roller cover 2-51, the dynamic damper 2-52 vibrates and the electrification roller cover 2-51 doesn't. Therefore, the amplification of vibration resulting from transmission to other container, etc., can be prevented.
