The figure shows one embodiment of the present invention, in which a toner cartridge 2 containing a powder toner 1 is constituted by an elongated cylindrical hollow container having a flat side wall 4, and one end of the toner cartridge 2 is provided with a toner powder. A handle 3 is installed so that the cartridge 2 can be easily rotated. The side wall 4 of the toner cartridge 2 has an opening 5 for discharging the toner 1.
The opening 5 is covered with an adhesive seal member 6 to prevent the toner 1 from leaking.
A circular bracket 8 is provided at the mounting opening of the developing machine hopper 7 to which the toner cartridge 2 is mounted, except for a portion 8a. The developing device hopper 7 is located above the developing device 21 provided adjacent to the photoreceptor drum 20, and develops the electrostatic latent image formed on the photoreceptor drum 20 through the exposure slit 22 with toner. (In FIG. 4, 23 is a transfer corotron; 2 is a transfer corotron;
4 indicates the registration role). The bracket 8 is provided with a slit 9 along its outer periphery, and is rotatably installed by a support member 10 that engages with the slit 9. Further, two take-up rolls 11 made of, for example, rubber are rotatably installed on the bracket 8 by a support member 12 via a roll shaft 14, and the support member 12 is provided with a support member 12 between the support member 12 and the bracket 8. It is biased downward by two compression springs 13 applied thereto. The roll shaft 14 is provided with a slit 15 into which one end of a sealing member 6 covering the opening 5 of the toner cartridge 2 is inserted.

When installing the toner cartridge 2, insert the tip of the toner cartridge 2 into the installation opening of the hopper 7, and insert one end of the seal member 6 into the slit 15 formed in the roll shaft 14 of the take-up roll 11. 1 or 3 a) Push the toner cartridge 2 into the hopper 7. The take-up roll 11 is brought into close contact with the side wall 4 of the toner cartridge 2 by the force of the compression spring 4.
rotates clockwise to wind up the seal member 6 (FIG. 3 B), and the opening 5 of the toner cartridge 2 opens in accordance with the winding (FIG. 3 A and B correspond to A in FIG. 2 A). -A sectional view). As described above, after the toner cartridge 2 is completely set in the hopper 7, the toner cartridge 2 is rotated 180 degrees clockwise together with the bracket 8 using the handle 3 (from A to B in Figure 2). ), the opening 5 faces down and supplies toner to the developing device 21. On the other hand, when removing the toner cartridge 2, rotate the toner cartridge 2 counterclockwise 180 degrees together with the bracket 8, contrary to the setting process, and then use the handle 3 to move the toner cartridge 2 to the hopper 7. When you extract it from
An adhesive seal member 6 closes the opening 5 of the toner cartridge 2. Therefore, scattering of the residual toner in the toner cartridge 2 can be prevented.

The bracket 8 has a pair of balls 25 that are pushed from below by the toner cartridge 6, and the balls 25 push the back surface of the bracket 8, so that when the bracket 8 is rotated by the rotation of the toner cartridge 2,
In the positions A and B of FIG. 2, the ball 25 can fall into the recess 8b to perform the stop function. Also, unlike the above embodiment,
If the toner cartridge is inserted with its opening facing downward and the take-up roll is correspondingly provided below the installation opening, the rotation operation of the toner cartridge and bracket can be omitted.
