SHEET DRYING APPARATUS AND IMAGE FORMING SYSTEM PROVIDED THEREWITH

Abstract: a sheet drying apparatus includes a conveyance portion, a drying portion, and a sheet lift sensing mechanism. the conveyance portion has a conveyance member that moves while holding a sheet having an image formed on it with ink containing moisture. the drying portion is arranged opposite the conveyance member and heats and dries the sheet. the sheet lift sensing mechanism includes a sheet lift sensor having a light emitter and light receiver opposite each other in the width direction of the sheet horizontally orthogonal to the conveyance direction and a sensing assist member that protrudes from above into a conveyance space above the conveyance member and that contacts a lifted part of the sheet to rotate it in a horizontal direction. the distance from the conveyance member to the sensing assist member is smaller than the minimum height of the conveyance space.
