    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 carrier driver includes an image carrier, a first power transmitter, a rotator, a second power transmitter, and a damper. The image carrier is configured to rotate by power generated by a driving source. The first power transmitter is configured to transmit the power from the driving source to the image carrier. The rotator is disposed further downstream than the image carrier in a flow of power transmission. The second power transmitter is configured to transmit the power from the image carrier to the rotator. The damper is disposed in the image carrier and is configured to attenuate an oscillation associated with the power transmission and transmitted to the image carrier.
