Sheet feeding apparatus, image forming apparatus, and image forming system

An image forming apparatus comprising:

• a front edge air part that blows front edge air, along a conveying direction of a sheet stacked, to a front edge side of the sheet;
• side edge air parts that are provided to face each other along an orthogonal direction to the conveying direction of the sheet and blow side edge air, along the orthogonal direction, to respective side edge sides of the sheet;
• a suction part that suctions, by a negative pressure, the sheet to which the front edge air and the side edge air are blown;
• and
• a conveyer that suctions and conveys the sheet suctioned by the suction part, wherein
• the front edge air and the side edge air are blown to the sheet to float the sheet in a posture in which a portion protruding from the conveyer of the sheet is lower than a conveying surface of the conveyer.
