Abstract

In a one-face mode, a first sheet discharge portion arranged on an upper face of an apparatus body, or a second sheet discharge portion arranged in the apparatus body so as to be freely opened and closed is opened, and a sheet forming an image on one surface thereof is discharged to this second sheet discharge portion. In a both-face mode, a sheet forming images on both surfaces thereof is conveyed to the first sheet discharge portion through a sheet discharge path formed by closing the second sheet discharge portion. When it is detected in the both-face mode that the second sheet discharge portion is opened on the basis of a detecting signal from a second sheet discharge portion open and close detecting portion, a controller controls the rotating direction of a forward and reverse rotatable conveying device on the basis of timer information from a timer device at the detecting time and the sheet forming the image on one surface thereof is conveyed to the first sheet discharge portion or the second sheet discharge portion, or a both-face conveying portion.
