部材であるが、省略してもよい。Next, the toner supply device a will be explained with reference to FIGS. 2 to 7. The toner cartridge 9 (see FIGS. 5 to 7) has a toner supply port 92 formed in the longitudinal direction of a cylindrical body 91 made of a non-magnetic material such as paper or plastic, and the supply port 92 is covered with a peelable seal. It is formed by sealing with a member 93 and further sealing both ends of the cylindrical body 91 with seven flanges 94 and 95. 7. The outer diameter of the flange 94 is the same as that of the cylinder 91.
is formed larger than the outer diameter of the
Further, the flange 94 is provided with a groove 97 into which the tip of the pull-out portion 93a of the seal member 93 is inserted. In addition, two protrusions 98.
99 is provided, and a cap 100 is further fitted. On the other hand, the container 10 (see FIGS. 2 to 4) is formed by supporting a cylinder 101 with side plates 102 and 103, and the side plate 102 is provided with grooves 106 and 10 through which the protrusions 98 and 99 can pass. . Further, the side plate 103 of the container 10 is provided with a stopper 104 that engages with the protrusion 98 and a stopper 105 that engages with the protrusion 99. Note that 108 (see FIG. 1) is a guide member that guides the protrusion 99, but it may be omitted.

Align the protrusions 98 and 99 of the toner cartridge 9 with the grooves 101 and 102 of the container 10, respectively, and then push it in until the 7 langes 94 come into contact with the end surface of the container 10 (see FIG. 3). Then, pull out the tip of the pull-out part 93a. After peeling off the sealing member 93, the cartridge 9 is rotated in a predetermined direction (the direction of the arrow y in FIG. 4) to cause the toner 5 to fall from the toner supply port 92. Here, the protrusion 99 is the stopper 1
Since its position is regulated by 04, the toner supply port 9
2 is set at a predetermined position, and a stopper 105 prevents the cartridge 9 from rotating in the opposite direction.

９９Ｂ、 ９９０は円周方向の位置が互いに異なってい
る。First, toner cartridges 9A, 9B, and 90 of each color are prepared. All of the cartridges have the same shape and dimensions, but one of the two protrusions is 98A, 98.
B, 990 are formed at the same position, and the other protrusion 99A1
99B and 990 have different positions in the circumferential direction.
（第９図）一方トナーカートリッジを受は取る側におい
