Abstract:
1. An image forming apparatus, comprising: a main body; a photoconductive medium disposed in the main body; a charging device configured to charge the photoconductive medium to a predetermined electrical potential; a scanning device configured to scan the charged photoconductive medium with light corresponding to image data to form an electrostatic latent image on the photoconductive medium; a developing device configured to form a visible image on the photoconductive medium by supplying developer to the photoconductive medium; a transfer device configured to transfer the visible image from the photoconductive medium to a printing medium; a fixing device configured to fix the visible image on the printing medium; a decurl device configured to correct a curl of the printing medium, the decurl device comprising at least a first decurl roller, a second decurl roller rotatably disposed opposite the at least first decurl roller, with each of the first decurl roller and the second decurl roller being rotatably disposed in the decurl device, and at least one corresponding curved member having a predetermined curvature along which the medium travels, the at least one corresponding curved member including a first decurl portion and a second decurl portion forming a concave decurl path opposite a duplex printing guide device, the printing medium is delivered along the concave decurl path formed between at least the first and the second decurl roller and the first and second decurl portions, the first and the second decurl portions arranged flanking each other, or flanking each other and having at least the first decurl roller therebetween; a discharging device configured to discharge the printing medium outside of the main body and to reverse a transport direction of the printing medium when a duplex printing is implemented; and the duplex printing guide device disposed between the fixing device and the discharging device, the duplex printing guide device being configured to guide the printing medium away from the decurl device when the transport direction of the printing medium is reversed for the duplex printing.
