Abstract
An image forming apparatus includes a fixing member having a cylindrical or annular shape for fixing an image onto a sheet which is in pressure contact with an outer surface thereof; and a heating source for heating the fixing member to a fixing temperature. A duct is provided in a position facing the fixing member with respect to a width direction perpendicular to a circumferential direction of the fixing member and which has an inlet for taking in fine particles generated from the fixing member. 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.
