Image forming apparatus

摘要

An image forming apparatus includes a cylindrical or annular fixing member (10) and a heating source for heating the fixing member (10) to a specified target temperature, so that a conveyed sheet is brought into pressure contact with an outer surface of the fixing member (10) to fix an image onto the sheet. The fixing member (10) includes a cylindrical or annular base material (11), a rubber layer (12) with elasticity, and an outer layer (13) for aiding release of the sheet. An end portion (12e) of the rubber layer and an end portion (13e) of the outer layer are each positioned inner than an end portion (11e) of the base material with respect to a width direction (C) perpendicular to a circumferential direction on the base material (11). A filter member (14) capable of trapping ultra fine particles generated from the rubber layer (12) is provided on the base material (11) in a position facing the end portion (12e) of the rubber layer (12) along the circumferential direction.
