Toner cartridges and the like in which a rotating shaft such as a transfer roller is set are widely used, but in order to prevent the powder 2 adhering to the peripheral surface of these rotating shafts 1 from mixing in the bearing portion 3 and hindering the rotation, A seal portion 5 for sealing the powder 2 is provided inside the bearing portion 3 (for example, the left and right side plates 4 of the toner tank) so that the powder does not leak from the seal portion 5 to the bearing portion 3 side. (See FIGS. 10 and 11)

The release paper 7'is peeled off and adhered to the inner peripheral surface of the concave portion 5a. At this time, in order to prevent powder leakage, the powder seal piece a should be wrapped as much as possible on the upper surface side of the rotary shaft 1. The left and right ends are folded back and adhered to the left and right side ends of the recess 5a (see (a) and (b) of FIG. 9), the work is difficult to make and requires time and skill. Currently, the number of normal workers is about 500 per day, and the number of skilled workers is about 800 at last.
【０００７】全て手作業であるため、仕上りが不均等で

大変となっていた。Only a small powder seal piece of about 5 × 50 × 3 mm is attached to the seal portion, but the toner cartridge itself to be attached, for example, is bulky in volume, so a wide working space is required. age,
For example, if one worker attaches a seal piece to 500 to 800 toner cartridges, naturally 500 to 800
A place for temporarily placing 800 toner cartridges is required, and a work space having a vast area is required when a working space of 10 to several hundred workers is provided. Therefore,
Although it is unavoidable to disperse them in rural areas in order to secure places and personnel, it is difficult to move and transport the bulky toner cartridge as described above.
