A toner cartridge used with an electrophotographic image forming apparatus includes 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 and to guide the toner toward the developing 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.
