Abstract: An image forming apparatus in which paper fed from a paper feeder is transported to image forming portions. A toner image is formed on the paper, and a pair of paper discharge rollers of a discharge unit are disposed at the rear end of a paper storing unit to discharge the paper into the paper storing unit. Preferably, the paper storing unit is disposed inside of the apparatus, with a lid or panel covering an access opening after the paper discharge operation has been completed, the paper storing unit is withdrawn from the apparatus; and/or feeds a stack of paper outside the apparatus upon opening of the panel. Therefore during the image forming operation, the leakage of noise made in the apparatus is prevented or reduced. Furthermore, since paper is discharged toward the front of the image forming apparatus, the width of the apparatus is minimized.
