PROBLEM TO BE SOLVED: To facilitate reproduction work of a toner cartridge to exert an effect on reuse of resources.SOLUTION: A toner discharge port sealing member 1 comprises: a frame body 10 that includes an opening 11 corresponding to the contour of a toner discharge port; a release sheet 20 that has the same shape as the rear face of the frame body 10; a strip-like seal member 30 that extends from one end 13 (right end) to the other end 14 (left end) of the frame body 10 and is folded at the other end 14, and has a length exceeding the right end; and a guide member 40 that has a slit 41 through which the strip-like seal member 30 can be inserted. The frame body 10 includes an adhesive layer on the front face 15 and the rear face 16, respectively, and the guide member 40 is bonded so that the slit 41 protrudes to the outside. The strip-like seal member 30 is attached to the front faces 12 of the frame body 10 while folded into two; a tip part 33 is inserted into the slit 41 of the guide member 40 from the front face side to the rear face side, and is stretched so that a portion from a folding part 32 to the tip part 33 is extended flat.SELECTED DRAWING: Figure 1 【課題】トナーカートリッジの再生作業が容易で資源の再利用に効果を発揮する。【解決手段】トナー排出口封止部材１は、トナー排出口の外形に対応する開口部１１を備える枠体１０と、枠体１０の裏面と同一形状の剥離紙２０と、枠体１０の一端（右端）１３から他端（左端）１４まで達したところで折り返されて右端を越える長さを有する帯状シール部材３０と、帯状シール部材３０を挿通させることのできるスリット４１を有するガイド部材４０とから構成される。枠体１０は、表面１５及び裏面１６に粘着剤層を備え、ガイド部材４０がスリット４１を外へはみ出す様に貼り付けられる。帯状シール部材３０は、二つ折りされた状態で枠体１０の表面１２に取り付けられ、先端部３３をガイド部材４０のスリット４１に対して表面側から裏面側へと挿通させ、折り返し部３２から先の部分がフラットに伸びた状態に引っ張っておく。【選択図】 図１
