Patent ID: 7099612

Claim:
A toner cartridge used with an electrophotographic image forming apparatus having a photosensitive drum, comprising: a developing roller that develops an electrostatic latent image formed on an outer circumferential surface of a photosensitive drum; a toner supplying roller that supplies toner onto the developing roller; a main chamber that stores the toner; a guide member that is disposed under the toner supplying roller to receive the toner from the main chamber and to guide the toner toward the developing roller through the toner supplying roller; a toner recovery chamber that is formed under the guide member to form a space where the toner remaining on the guide member, which is not supplied to the developing roller, can accumulate; a recovery roller that rotates in the toner recovery chamber to return the toner in the toner recovery chamber to the main chamber; and a toner blocking film that is installed on a lower portion of the guide member to prevent the toner from directly leaking to the toner recovery chamber from the main chamber.
