Abstract:
1. An image developing apparatus comprising: an upper case; a lower case disposed on and fixed to a lower side of the upper case, and internally housing a developing agent, and having an opening; a photoconductive drum disposed on the upper case for forming an electrostatic latent image on a surface thereof; a charging roller disposed on one side of an outer circumference of the photoconductive drum, for charging the photoconductive drum; a developing roller having one part exposed through the opening of the lower case to cooperate with the photoconductive drum, and developing the electrostatic latent image; a fixing bracket coupled to an upper side of the lower case and supporting a regulating blade which regulates a thickness of a developing agent layer formed on a surface of the developing roller; and a scattering preventing unit disposed between the photoconductive drum and the developing roller, to prevent scattering of the developing agent supplied by the developing roller, the scattering preventing unit including a blocking curtain covering a part of the opening and having one side in contact with the outer circumference of the photoconductive drum and the fixing bracket supporting the other side of the blocking curtain, the blocking curtain including a supporting portion supported on the fixing bracket, and a bending portion having one end of the supporting portion bent to contact the photoconductive drum; wherein one end of the scattering preventing unit is attached to a top surface of the fixing bracket and the other end of the scattering preventing unit is disposed toward the photoconductive drum.
