ABSTRACT:
A latent electrostatic image developing device, including a cartridge loading section having an open top and a toner cartridge adapted to be removably loaded into the cartridge loading section. The cartridge loading section includes a pair of upwardly facing supporting shoulder surfaces extending longitudinally in laterally spaced-apart relationhsip, guiding side surfaces rising respectively from the outside edges of the shoulder surfaces, and a guiding rear surface extending between the rear ends of the guiding side surfaces. The guiding side surfaces respectively having holding protrusions provided at their front end portions. Engaging protrusions are provided behind of the holding protrusions at a predetermined distance therefrom. The toner cartridge includes a loading flange having side flange portions disposed in correspondence to the pair of shoulder surfaces and a closing member extending above the loading flange while surrounding both sides and the rear end thereof. The closing member is formed of a flexible material such as sponge rubber and extends beyond the outside edge of the loading flange.
