PROBLEM TO BE SOLVED: To utilize a sealing material for any recycled cartridge whose an aperture part shape is different and to prevent a pollution by a toner by applying an adhesive or sticking a double coated adhesive tape on the front and the back surfaces of a plate material having an aperture part, disposing a sealing material main body on the front surface and peeling paper on the back surface and making the sealing material a structure where the adhesive or the tape not made to exist on the back surface of the sealing material main body at the exposed part of the aperture part. SOLUTION: A sealing material main body 10 is stuck to a plate material 20 through an adhesive applied to the upper surface of the plate material 20 or a double coated adhesive tape stuck thereto. When a pull-out operation part 11 is pulled out by a user, the main body 10 is torn in the width of the operation part 11 along a perforation from the base part to release the shielding in an aperture part 23 of the plate material 20 which newly becomes a toner supplying aperture part. Since a part facing to the aperture part 23 of the plate material 20 on the back surface of the main body 10 is not coated with the adhesive at this time, a situation that the toner adheres to the part and is pulled out to the outside in the case of unsealing work is prevented. |
