Abstract
Disclosed is a disposable sheet cassette and an image forming apparatus in which such a sheet cassette is preferably employed. The sheet cassette is comprised of a cassette box capable of accommodating a plurality of sheet materials and having a flange portion extending outwards from the cassette box, an adhesive layer formed on the flange portion, and a sheet cover bonded on the adhesive layer for covering an opening of the sheet cassette. A portion of the sheet cover can be repeatedly separated from or applied to the adhesive layer to open or close the opening. The image forming apparatus is provided with a take-up roller movable above the sheet cover for winding the sheet cover, a pair of roller supports for rotatably supporting the take-up roller, a driving mechanism for moving the roller supports and for rotating the take-up roller, and a control system for operating the driving mechanism so that the take-up roller can wind the sheet cover after the sheet cassette has been charged in the apparatus.
