Abstract
A sheet transport apparatus including an upstream-side transport unit configured to hold a sheet and transport the sheet by rotating; a downstream-side transport unit configured to hold the sheet and further transport the sheet by rotating, the downstream-side transport unit being arranged at such a position that an unrestrained transport section is formed where the sheet is not held downstream in transport direction from the upstream-side transport unit; an upstream-side air-feed unit configured to form an air flow that flows downstream in transport direction on both sides of a transport plane of the sheet in the unrestrained transport section; and a controller configured to control the upstream-side air-feed unit to start forming an air flow before a leading edge of the sheet reaches the unrestrained transport section from the upstream-side transport unit, and to stop the air flow before a trailing edge of the sheet reaches the unrestrained transport section.
