摘要： A plurality of first viscoelastic bodies are disposed in insertion holes of a first rotary member. A plurality of second viscoelastic bodies are disposed in guide holes of a second rotary member. Each of the first and the second viscoelastic bodies has an elastic coefficient changing in accordance with aging due to use. A guide member moves a contact member along the insertion hole and the guide hole. The contact member applies a compressive load to the first viscoelastic body. The aging of the second viscoelastic body due to the compressive load applied thereto moves a position of the first viscoelastic body where the compressive load is received from the contact member toward a farther side from a rotational shaft side.

摘要： An image forming apparatus includes an image carrier that rotates by power generated by a driving source. A power transmission system transmits the power from the driving source to the image carrier. The power transmission system includes a coupling member to attenuate oscillation. The coupling member includes a viscous fluid, male and female fittings, and a rotating resistor. The viscous fluid provides a resistance against rotation of the image carrier. The male and female fittings are mutually fitted and rotatably supported on a rotary shaft of the image carrier penetrating through the male and female fittings in a direction in which they are mutually fitted. The rotating resistor is accommodated together with the viscous fluid in an accommodation space defined by a recess of the male fitting and a bottom inner surface of the female fitting. The rotating resistor integrally rotates with the rotary shaft.

摘要： An image forming apparatus includes a driving source, a first rotator, a first power transmission system, at least one second rotator, a second power transmission system, and a damper. The driving source generates power. The first rotator is drivingly rotated by the power generated by the driving source. The first power transmission system transmits the power from the driving source to the first rotator. The second rotator is further downstream than the first rotator in a flow of power transmission. The second power transmission system transmits the power from at least one of the first power transmission system and the first rotator to the at least one second rotator. The damper attenuates oscillation between the first power transmission system and the second power transmission system or between the first rotator and the second power transmission system.
