What is claimed is: 1. An image forming apparatus, comprising: a toner cartridge storing a toner and having a toner supply window to supply the toner; a housing detachably accommodating the toner cartridge; and a toner receptacle provided to the housing to receive the toner that leaks from the tone
What is claimed is: 1. An image forming apparatus, comprising: a toner cartridge storing a toner and having a toner supply window to supply the toner; a housing detachably accommodating the toner cartridge; and a toner receptacle provided to the housing to receive the toner that leaks from the toner cartridge, when the toner cartridge is attached to or detached from the housing, wherein the toner cartridge comprises: a shutter coupled to the toner cartridge, opening and closing the toner supply window, when the toner cartridge is attached to or detached from the housing, respectively; and a toner remover coupled to the housing to remove the toner that leaks from the toner cartridge, when the toner cartridge is attached to or detached from the housing. 2. The image forming apparatus according to claim 1, wherein the toner cartridge comprises a toner transfer member installed in the toner cartridge to transfer the toner stored in the toner cartridge to the toner supply window. 3. The image forming apparatus according to claim 2, wherein the toner transfer member is a rotatable auger. 4. The image forming apparatus according to claim 1, wherein the toner remover is disposed on the housing, and is provide near an outer periphery of the toner cartridge so as to remove the toner that leaks through the toner supply window and the shutter, when the toner cartridge is attached to or detached from the housing. 5. The image forming apparatus according to claim 4, wherein the toner remover comprises a toner removing member protruding from an inner periphery of the housing. 6. The image forming apparatus according to claim 5, wherein the toner receptacle is detachably coupled to the housing. 7. The image forming apparatus according to claim 4, wherein the toner remover comprises: an opening formed at one side of the housing corresponding to a moving trajectory of the shutter when the toner cartridge is attached to or detached from the housing; and a biasing portion provided to the opening pressing the shutter to remove the toner adhered to the shutter when the toner cartridge is detached from the housing. 8. The image forming apparatus according to claim 7, wherein the biasing portion comprises: a first member contacting the shutter to remove the toner leaking from the housing; a second member coupled to the housing to cover the opening; and a resilient member installed between the first member and the second member biasing the first member against the opening. 9. The image forming apparatus according to claim 8, wherein the first member has an interfering portion interfering with the housing to restrict a movement of the first member to prevent the first member from passing through the opening. 10. The image forming apparatus according to claim 9 wherein the interfering portion and the resilient member maintain the first member at a constant height. 11. The image forming apparatus according to claim 9, wherein the first member has a convex portion protruding towards the opening. 12. The image forming apparatus according to claim 11, wherein the convex portion point-contacts the shutter. 13. The image forming apparatus according to claim 12, further comprising a toner storing portion storing the toner removed by the first member. 14. The image forming apparatus according to claim 13, wherein the toner storing portion is detachably coupled to the housing. 15. A cleaning unit for use in an image forming apparatus to remove residual toner from an outer portion of a toner cartridge, comprising: cleaning means for removing the residual toner on the outer portion of the toner cartridge, the cleaning means contacting the toner cartridge during removal and installation; a housing supporting the cleaning means and detachably accommodating the toner cartridge in the image forming apparatus; and collecting means for collecting the residual toner removed by the cleaning means, wherein the collecting means contact the housing. 16. The cleaning unit of claim 15, wherein the collecting means is integrally formed with the housing. 17. The cleaning unit of claim 15, wherein the collecting means is detachably coupled with the housing. 18. An image forming apparatus utilizing a replaceable toner cartridge to supply toner to form toner images, comprising: a housing to accommodate the toner cartridge and supply the toner from the toner cartridge to the image forming apparatus; a cleaner to remove residual toner from an outer surface of the toner cartridge during installation and removal of the toner cartridge; and a collector to store the removed residual toner cleaned from the outer surface of the toner cartridge. 19. The image forming apparatus of claim 18, wherein the collector is detachably coupled with the housing. 20. The image forming apparatus of claim 18, wherein the cleaner is biased against the outer surface of the toner cartridge during installation and removal. 21. An image forming apparatus, comprising: an image developer cartridge; a bottle-type toner cartridge to store toner, and provided with a toner supply window to supply to toner to the image developer cartridge; a housing to accommodate the toner cartridge; a shutter disposed on the housing, to open or close the toner supply window, when the toner cartridge is installed in or removed from the housing; a toner remover disposed on the housing and provided near an outer periphery of the toner cartridge, to remove residual toner from an outer surface of the toner cartridge, when the toner cartridge is installed in or removed from the housing; and a toner receptable coupled to the housing, to store the residual toner removed from the outer surface of the toner cartridge. 22. The image forming apparatus of claim 21, wherein the toner remover comprises: a body installed to the housing to cover an opening formed at one side of the housing; a toner removing member arranged to protrude, via the opening of the housing, and biased to press against the outer surface of the toner cartridge to remove the residual toner that leaks through the toner supply window and the shutter, when the toner cartridge is installed in or removed from the housing. 23. The image forming apparatus of claim 21, wherein the toner cartridge is provided with a rotatable auger to transfer the toner stored in the toner cartridge to the toner supply window.
