Claim:
1. A sheet conveying device comprising: a switchback unit configured to switch a sheet conveying direction; a first conveying path for conveying a sheet to the switchback unit; a second conveying path for conveying a sheet after the sheet conveying direction is switched by the switchback unit; a switching member disposed between the first conveying path and the switchback unit, the switching member having a rotation fulcrum axis extending in a sheet width direction crossing the sheet conveying direction and rotating about the rotation fulcrum axis so as to switch between a first attitude for guiding a sheet from the first conveying path to the switchback unit and a second attitude for guiding a sheet from the switchback unit to the second conveying path; a unit guide surface for guiding a sheet guided from the first conveying path to the switchback unit and for guiding a sheet guided from the switchback unit to the second conveying path; a sheet guiding surface formed on the switching member so as to face the unit guide surface, for guiding a sheet guided from the first conveying path to the switchback unit and for guiding a sheet guided from the switchback unit to the second conveying path; and at least one convey roller including a rotation shaft disposed on the same axis as the rotation fulcrum axis of the switching member, an outer circumference surface of the convey roller protruding more than the sheet guiding surface, the at least one convey roller being disposed at a predetermined interval from the unit guide surface.
