Imaging forming apparatus

DETAILED DESCRIPTION It is an object of the invention to provide an image forming apparatus in which discharged sheets can be easily distinguished, and which has a reduced number of parts and can be economically produced.
In a first aspect of the invention, an image forming apparatus comprises: an image forming section for forming an image on a sheet; a discharge tray for receiving the sheet on which an image is formed; a first conveying path for guiding the sheet from the image forming section to the discharge tray so as to place the sheet on the discharge tray with directing an image forming face of the sheet in one of upward and downward directions; a second conveying path for reversing the sheet to guide from the image forming section to the discharge tray so as to place the sheet on the discharge tray with directing the image forming face in the direction opposite to the direction in which the first conveying path guides the sheet to the discharge tray; and switching means for switching over the first conveying path and the second conveying path, and the apparatus further comprises moving means for moving the discharge tray between a position where a sheet discharged from a discharge port of the first conveying path is received, and another position where a sheet discharged from a discharge port of the second conveying path is received.
According to the first aspect of the invention, a sheet on which an image is formed is guided by the first or second conveying path and then discharged to the discharge tray.
Although the apparatus has two discharge ports, the single discharge tray can receive sheets discharged from the discharge ports, because the discharge tray can be moved by the moving means.
Therefore, it is possible to provide an image forming apparatus which can be produced in a simple configuration and at a low cost.
In a second aspect of the invention, the image forming apparatus is characterized in that the discharge port of the first conveying path and the discharge port of the second conveying path are vertically arranged on a side of the image forming apparatus, and the moving means moves the discharge tray up and down
