Abstract:
An image forming apparatus includes a fixing member for fixing an image onto a sheet in pressure contact with an outer surface thereof; and a heating source for heating the fixing member. 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. A filter member is provided inside the duct and which can trap the fine particles which flow through the duct. An exhaust fan is provided in the duct upstream or downstream from the filter member for generating an air flow going from the inlet to an outlet of the duct. A control section controls the operation of the exhaust fan according to initial burst conditions under which the fine particles are emitted from the fixing member.
