Abstract:
An image forming apparatus comprising:a static latent image support:a developer support which is supported in a developing unit and retains and conveys a developer so as to produce a visual image by developing the static latent image formed on the peripheral surface of the static latent image support with the developer from the developer support,a sealed viscous fluid damper having a viscous fluid sealed therein provided coaxially with a rotary shaft of the developer support,wherein the sealed viscous fluid damper includes an outer sleeve which includes an outer peripheral surface of the damper coaxially provided with the rotary shaft and being rotatable therewith;a rotary inertial body having a smaller outside diameter than the inside diameter of the outer sleeve and coaxially mounted inside the outer sleeve so as to be freely rotatable; anda viscous fluid sealed between an inner surface of the outer sleeve and the rotary inertial body.
