Patent ID: 8509646

Claim:
An image forming apparatus, comprising: a fixing device to fix an image to a sheet with heat and pressure; an air exhaust member to exhaust air having a high temperature and moisture generated by the fixing device; an exhaust fan provided in the air exhaust member, mounted at an angle to a sheet conveyance path internal to the apparatus above the fixing device, an exhaust airflow path internal to the apparatus narrowing toward a downstream side in an air exhaust direction of the exhaust fan, and a deflection plate provided across the exhaust airflow path downstream from the exhaust fan, wherein the exhaust air discharged from the exhaust fan is deflected substantially orthogonally by the deflection plate, and wherein the deflection plate is provided with a deflector section substantially arc-shaped in cross-section to reduce pressure loss at a portion where air pressure of the exhaust fan is received.
