An exhaust fan is provided inside the duct or in an outlet of the duct for generating an air flow going from the inlet to the outlet of the duct. A first filter member is provided upstream or downstream from the exhaust fan inside the duct and the first filter can trap the fine particles which flow through the duct getting on the air flow. A control section controls an amount of the air flow passing through the first filter member according to initial burst conditions under which the fine particles are emitted from the fixing member.

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.
