Blowing tube, blowing device, and image forming apparatus

A blowing tube comprising:

• a passage portion that includes a passage space through which an inlet port taking in air is connected to an outlet port that outputs the air taken in by the inlet port and has an opening shape which is long in one direction, and through which air flows;
• and
• a plurality of flow control members that are provided in portions of the passage space of the passage portion which are positioned at different positions in an airflow direction, and that control a flow of air,
• wherein one of the plurality of flow control members is provided as a downstream-most flow control member such that the outlet port is blocked by a multi-hole member having a plurality of air holes, and
• wherein each of the plurality of air holes of the downstream-most flow control member is configured as a through hole consisting of hole portions each having an opening area which is identical in an air passing direction, the hole portions being aligned such that the opening area of the through hole decreases stepwisely toward the downstream side in the air passing direction.
