<p>A toner cartridge (30) is adapted to be loaded detachably into the cartridge loading section of a latent electrostatic image developing device comprising a cartridge loading section (46) having an open top. The cartridge loading section (46) includes a pair of upwardly facing supporting shoulder surfaces (52,54) extending longitudinally in laterally spaced-apart relationship, guiding side surfaces (56,58) rising respectively from the outside edges of the shoulder surfaces (52,54) and a guiding rear surface (70) extending between the rear ends of the guiding side surfaces (56,58). The guiding side surfaces (56,58) have respective holding protrusions (72,74) provided at their front end portions. Engaging protrusions (76,78) are provided behind of the holding protrusions (72,74) at a predetermined distance therefrom. The toner cartridge (30) includes a loading flange (92) having side flange portions (94,96) disposed in correspondence to the pair of shoulder surfaces and a closing member (114) extending above the loading flange (92) while surrounding its both sides and rear end. The closing member (114) is formed of a flexible material such as sponge rubber and bulges beyond the outside edge of the loading flange (92). <IMAGE> <IMAGE></p> |
