A sheet post-processing apparatus includes a pair of a conveying upper guide and a conveying lower guide which guides a sheet conveyed by an intermediate roller conveying the sheet, a sheet discharging upper rotating body and a sheet discharging lower rotating body which discharge the sheet on the downstream side of the conveying upper and lower guides, an arm which has the sheet discharging upper rotating body and is displaceable in upward and downward directions, a cam which lifts the arm upward to separate the sheet discharging upper rotating body from the sheet discharging lower rotating body, a stapler which is provided on the downstream side in a sheet conveying direction lower than the intermediate roller and performs processing to the sheet stacked in the conveying lower guide, a link portion which displaces upward the conveying upper guide when the arm is displaced by the cam, and a link lever. In the sheet post-processing apparatus, the stapler, the sheet discharging upper rotating body, and the sheet discharging lower rotating body are orderly placed on the downstream side.
