BLAST PIPE, BLOWER, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a blast pipe having an inlet and an outlet connected by a passage space having at least one bent portion and having different opening shapes, and configured to prevent wind speed of the air discharged from the outlet from being relatively reduced especially at a longitudinal end of the outlet closer to the inlet.SOLUTION: A blast pipe includes a plurality of control sections. One of the control sections located in the uppermost stream partitions a passage space in a passage part, while crossing a part of the bent passage space, and has a long and thin gap extended in the crossing direction to allow the air to pass. The control section located in the uppermost stream is arranged so that an imaginary straight line connecting both ends of the gap is located downstream in a flow direction of the air passing through the bent portion of the passage space with respect to an inside end closer to the bent portion of the passage space in an inlet.
