<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus with which a reduction in the concentration of ozone remaining in each process print unit and the uniformization of ozone concentration are realized. <P>SOLUTION: The ozone exhaust structure of the image forming apparatus 1 having the plurality of process print units 20 includes: a charger case (shielding part) 224 enclosing the needle-like electrode (electric field generating part) 222 of each process print unit 20 from one end to the other end; and an exhaust duct 110 communicating with the outside along the charger case 224 in order to discharge ozone generated by the charger case 224. The charger case 224 has a plurality of openings 225a, 225b, and 225c of different opening areas, which serve as air intake sections 225 through which outside air is taken into the case. The openings 225a, 225b, and 225c are made so as to extend from the F side of the charger case 224 to the R side of it. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
