PURPOSE:To supply a developing agent easily in a short time without causing scattering by encasing a double-case toner cartridge in a containing member, and bringing the openings into coincidence by rotating the cartridge in a prescribed amount. CONSTITUTION:A toner cartridge 21 is encased in a cylindrical part 7a of a containing member 7 through a hole 8 with the opening 1 of the outer case 2 facing upwards and with the opening 3 of the inner case 4 facing downwards. At this time, rotation of the inner case 4 is arrested by fitting stop pins 11a, 11b of the containing member 7 to engaging holes 5a, 5b of the inner case 4. Next, engaging pins 15a, 15b of the rotative sealing cover 22 are inserted into engaging holes 6a, 6b of the outer case 2 to couple with the outer case 2 and, at the same time, the rotative cover 22 is rotated along a guide groove 9 by introducing the rotation pin 14 to the guide groove 9. Then, only the outer case 2 is rotated 180 deg. and openings 1, 3, 12 come to the same position. Under this condition, the toner 20 falls down and fed to the toner container without scattering. |
