A double-surface printing apparatus, which is small-sized and has a simple construction to make it impossible to take out a sheet, of which one surface has been subjected to printing, from outside. The apparatus includes a paper discharge tray, to which sheets having been subjected to printing are discharged; a sheet reversing mechanism including a reversal/temporary storage unit for guiding a sheet in a direction different from a discharge direction toward the paper discharge tray, once exposing the sheet outside of the apparatus, and rotating conveying rollers in an opposite direction to thereby reverse the sheet; and a protective cover, which covers the sheet conveyed to the reversal/temporary storage unit so that a sheet, of which one-surface has been subjected to printing, cannot be taken out from outside.
