摘要： A fixing member according to the present invention is such one as is brought into pressure contact with a conveyed sheet to fix an image onto the sheet. The fixing member comprises a cylindrical or annular base material, a rubber layer provided so as to cover an outer surface of the base material and having elasticity, and an outer layer provided so as to cover an outer surface of the rubber layer for aiding release of the sheet. A siloxane content in a central section of the rubber layer is less than twice the siloxane content in an end portion of the rubber layer with respect to a width direction vertical to a circumferential direction on the base material.

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.
