AIR BLOWING SYSTEM AND IMAGE FORMING APPARATUS INCLUDING SAME

摘要

Disclosed is an air blowing system including: an air blowing device; a duct that guides air blown by the air blowing device; and a ventilation section disposed downstream of the duct in terms of an air blowing direction in which air is blown by the air blowing device so that the air blown by the air blowing device strikes and passes through the ventilation section, wherein the duct has a distorted portion where a part of an inner wall face of the duct located between the air blowing device and the ventilation section is distorted perpendicular or substantially perpendicular to the air blowing direction so that the air blown by the air blowing device flows perpendicularly or substantially perpendicularly to the air blowing direction. Also disclosed is an air blowing system including: an air blowing device; and a duct that guides air blown by the air blowing device, wherein the duct has an outer surface on at least a part of which there is provided a surface area reducing portion for reducing a surface area of a continuous face.
