Waste container and electrophotographic image forming apparatus including the same

An electrophotographic image forming apparatus using a developing agent formed by mixing a toner and a carrier, the electrophotographic image forming apparatus comprising:

• a plurality of photosensitive bodies on which electrostatic latent images are formed;
• a plurality of developing agent containers to be individually replaceable and to contain developing agents having different colors;
• a plurality of developing units to form toner images by transferring the toner of each of the developing agents supplied from the developing agent containers to the electrostatic latent images;
• a waste toner discharging member having a waste toner outlet through which a waste toner removed from the plurality of photosensitive bodies is discharged;
• a waste developing agent discharging member having a waste developing agent outlet through which a waste developing agent discarded from the plurality of developing units is discharged, and disposed below the waste toner outlet;
• and
• a detachable waste container having a first inlet corresponding to the waste toner outlet, a second inlet disposed below the first inlet to correspond to the waste developing agent outlet, a first region to receive the waste toner, and a second region to receive the waste developing agent, the second region being disposed within the first region and separated from the first region,
• wherein a bottom surface of the second region is at the same level as a bottom surface of the first region,
• wherein the second inlet is disposed below the first inlet,
• wherein the waste container further comprises a full sensing unit to detect whether the first region is full of the first waste, and
• wherein the full sensing unit comprises:
• an isolation chamber inside the first region, the isolation chamber having an opening formed below the first inlet and being in communication with the first region, the isolation chamber being isolated from the second region and the second inlet;
• and
• a sensor disposed in the isolation chamber to sense the first waste introduced through the opening.

A waste container to be detachably mounted on an electrophotographic image forming apparatus to electrophotographically print an image by using a developing agent formed by mixing a carrier and a toner and to receive therein a waste discharged during the printing, the waste container comprising:

• a single housing having a first region formed with a first inlet to receive a first waste and a second region formed with a second inlet to receive a second waste, the second region being disposed within the first region and separated from the first region,
• wherein a bottom surface of the second region is at the same level as a bottom surface of the first region,
• wherein the second inlet is disposed below the first inlet,
• wherein the waste container further comprises a full sensing unit to detect whether the first region is full of the first waste, and
• wherein the full sensing unit comprises:
• an isolation chamber inside the first region, the isolation chamber having an opening formed below the first inlet and being in communication with the first region, the isolation chamber being isolated from the second region and the second inlet;
• and
• a sensor disposed in the isolation chamber to sense the first waste introduced through the opening.
