主权项 1. An image forming apparatus comprising: an image forming unit disposed in a main body of the image forming apparatus, to form an image on a sheet; a sheet feeder including a pair of supporter members each including integrally formed therein: a rod supporter; anda sheet roll supporter disposed below the main body of the image forming apparatus to support a sheet roll formed of a continuous sheet and accommodated in an open region below the image forming unit disposed in the main body of the image forming apparatus,wherein the sheet feeder feeds the continuous sheet from the sheet roll supported by the sheet roll supporter to the image forming unit disposed in the main body of the image forming apparatus, to form an image thereon; a cutter to cut off a cut sheet of a predetermined length from the continuous sheet fed from the sheet roll; a sheet discharger disposed downstream from the image forming unit in a direction of conveyance of the sheet to discharge the cut sheet having the image formed thereon in a sheet discharging direction through a discharge opening of the main body of the image forming apparatus; a guide unit to guide the sheet discharged from the sheet discharger to the front of the main body of the image forming apparatus; and a stacking unit on which the sheet passing the guide unit is stacked, wherein upper and front parts of the sheet roll are covered with the guide unit and the stacking unit across a width direction of the sheet perpendicular to the sheet discharging direction, wherein the guide unit includes a discharge guide plate disposed downstream from the discharge opening of the main body and outside a front surface of the main body, the discharge guide plate including a guiding surface on which the sheet is guided downwards projecting gradually away from the front surface of the main body, wherein the discharge guide plate covers an upper part of an opening to the open region in which the sheet roll is accommodated, and the discharge guide plate is swingable away from the open region to uncover the upper part of the opening to the open region, wherein the stacking unit includes a sheet discharge bucket to collect sheets that have passed through the discharge guide plate,a discharge rod to support an upper end of the sheet discharge bucket, the discharge rod being supported by the rod supporter of each of the pair of supporter members, wherein the rod supporter that supports the discharge rod is disposed at a height that is substantially the same as that of the sheet roll supporter that supports the sheet roll, and the upper end of the sheet discharge bucket supported by the discharge rod is continuous with the discharge guide plate.
