ABSTRACT:
An image forming apparatus provided with a dust collecting part includes an ink cartridge having a wide array type ink jet head that is capable of ejecting ink over an entire lateral line that is perpendicular to a conveying direction of a recording medium at a time, and a main body case that supports the ink cartridge, a duct located under the wide array type ink jet head to extend in a longitudinal direction of the wide array type ink jet head; and a dust collecting part including a charging part disposed in the duct to charge impurities and electrodes disposed in the duct to adsorb the charged impurities The image forming apparatus includes a dust-collecting part that adsorbs the impurities over an entire region of the wide array type ink jet head, thereby effectively removing the impurities generated in large quantities and increasing a life span and a reliability of image forming apparatuses, since the dust collecting part is securely maintained during operation.
