摘要:
A thermal fixing unit provided with gas purification means for use in an image recording medium. The gas purification means traps gaseous component released from a developer sheet upon heating thereof. The purification means includes a duct body (44) disposed to surround a main frame of the thermal fixing unit (23), a support body (42) having one end connected to the duct body, a fluid passage (40) being defined between the main frame and the duct body, and the fluid passage (40) being connected between the one end of the support body and sheet inlet and sheet outlet of the thermal fixing unit, a gas venting fan (43) rotatably provided at the support body (42) for sucking fluid in the main frame through the sheet inlet, the sheet outlet and the fluid passage, and a filter member (45) disposed in the support body for trapping the gaseous component released from the developer sheet.
