Abstract
A developing cartridge for an electrophotographic image forming apparatus includes, a toner housing, a toner storage chamber, a toner feeding chamber, a feeding roller, a developing roller and a shielding device. One side of the toner housing has an opening, and the toner storage chamber and the toner-feeding chamber communicate with each other through a communication hole. The shielding device is installed within the toner storage chamber so as to move from a shielding position where it shields the communication hole to an opening position where it opens the communication hole. Accordingly, since the shielding member is capable of moving within the toner storage chamber, the user can save trouble of separating and removing the shielding member from the toner housing.
